A camper on top of a 400 foot cliff is enjoying the view. They look down and see a
bear at an angle 37 degrees. Approximately how far is the bear from the base of the
cliff? (Round your answer to the nearest foot.). REMEMBER THE UNITS
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer

Answer:
It's 76 degrees
Step-by-step explanation:
Thanks for branliest
Answer:
76
Step-by-step explanation:
the interior angles of a triangle always add up to 180 degrees, so all we have to do is add the 2 angle values that we know, so 48 + 56=104, then we subtract that from 180 to get 76. Hope this helps!
Solve super fast please
Answer:
x = 8
Steps:
(4x-2) + (17x+14) = 180
4x + 17x -2 + 14) = 180
21x + 12 = 180
21x = 180-12
21x = 168
x = 168/21
x = 8
Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answer:
Angle Z = 180-32 -90 = 58 degrees
sine (32) = y / 16
y = 16 * sine (32)
y = 16 * 0.52992
y = 8.47872
x^2 = 16^2 -y^2
x^2 = 256 -71.888
x^2 = 184.112
x = 13.568
Step-by-step explanation:
Answer:
x = 13·568, y = 8·47 and z = 58
Step-by-step explanation:
I don't think the question required you to use the Pythagoras theorem but here are some pointers anyway.
Okay, the Pythagoras theorem is quite simple: a² + b² = c²Where c is always the hypotenuse, a is the height or the opposite side and b is the base or the adjacent side. (I've attached a picture just in case) (It might look confusing but the way I've lettered them is taking the 90° angle to be on the right side)The a and b doesn't actually matter so don't think too much about which side is a and which one is b, they're more or less the same.The reason I said that this question might not solely require you to use the Pythagoras theorem is because you need to have two variables for the equation to work, maybe this is what got you confused.
For this question, you're required to use Tangents, Sines and Cosines, or you can combine this method and Pythagoras method.
Looking for x and y:Method one: Using Tangents, Sines and Cosines AND the Pythagoras theorem
Step 1: Looking for x(Using Sin, Cos and Tan)
To find the length of side x, we need to use the Cosine of 32°
Cos 32° = Adjacent side ÷ Hypotenuse
0·8480 = x/16
Make x the subject and multiply both sides by 16
0·8480 × 16 = x/16 × 16
13·568 = x
∴ side x is 13·568
Step 2: Looking for y( using the Pythagoras theorem)
a² + b² = c²
a = y, b = x = 13·568, c = 16
y² + 13·568² = 16²
y² + 184·0906 = 256
y² = 256 - 184·0906
y² = 71·9094
y = √71·9094
y = 8·4799
Method 2: Using Tan, Cos and Sin only
Step 1 remains the same as shown above; x = 13·568
Step 2: Looking for y
Y can be gotten by using the Sine of 32°
Sin 32° = Opposite ÷ Hypotenuse
Sin 32° = y ÷ 16
0·5299 = y/16
Make y the subject and divide both sides by 16
0·5299 × 16 = y/16 × 16
8·4784 = y
∴ y is equal to 8·4784
(I know there's a difference in points of the two values of y, but if you round them off to 2 decimal places we see it remains 8·47
2. Looking for z:
Using addition and subtraction
The simpler method would be to just add all the internal angles.
The little square in the corner tells us that that is a 90° angleThe internal angles of a triangle ALWAYS add up to 18032 + 90 + z = 180
122 + z = 180
z = 180 - 122
z = 58
∴ z is equal to 58°
Using Tan, Sin and Cos
The cosine of Z is equal to y divided by 16, where y = 8·47
Cos z = 0·5294
Make z the subject and divide both sides by Cos.
z = 0·5294/Cos
z = 58·04° (I just used the anti-cos to get this number. Press shift, and cos on your calculator then type 0.5294 in front of it)
Here there is also a slight difference in points between the two steps but if you round off step 2 to a whole number you get 58, so it's all good :)

Question 3 of 10
Which statement does not describe the relationship between genes and
inherited traits?
A. Some inherited traits are affected by more than one gene.
B. Individual genes carry the instructions for inherited traits.
C. Inherited traits carry the instructions for individual genes.
D. Some genes influence more than one inherited trait.
C. Inherited traits carry the instructions for individual genes is the statement that does not describe the relationship between genes and inherited traits. Genes carry the instructions for inherited traits, not the other way around.
How do you use the sum or difference identity to find the excat value of sin 165°
Answer:
[tex]\frac{1}{4}[/tex] ([tex]\sqrt{6}[/tex] - [tex]\sqrt{2}[/tex] )
Step-by-step explanation:
Using the addition formula for sine
sin(A + B) = sinAcosB + cosAsinB
Given
sin165° = sin(120 + 45)° , then
sin(120 + 45)°
= sin120°cos45° + cos120°sin45°
= sin60°cos45° - cos60°sin45°
= [tex]\frac{\sqrt{3} }{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex] - [tex]\frac{1}{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex]
= [tex]\frac{\sqrt{6} }{4}[/tex] - [tex]\frac{\sqrt{2} }{4}[/tex]
= [tex]\frac{1}{4}[/tex] ( [tex]\sqrt{6}[/tex] - [tex]\sqrt{2}[/tex] )

sin(A+B)/sin A cos B
= 1 + cot A tan B
how to verify the identity?
Answer:
see explanation
Step-by-step explanation:
Using the identities
sin(A + B) = sinAcosB + cosAsinB
cotA = [tex]\frac{cosA}{sinA}[/tex] , tanA = [tex]\frac{sinA}{cosA}[/tex]
Consider the left side
[tex]\frac{sin(A+B)}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB+cosAsinB}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB}{sinAcosB}[/tex] + [tex]\frac{cosAsinB}{sinAcosB}[/tex]
= 1 + [tex]\frac{cosA}{sinA}[/tex] . [tex]\frac{sinB}{cosB}[/tex]
= 1 + cotA tanB = right side , thus verified

Answer:
f(1) = 2, f(4) = 8
Step-by-step explanation:
f(1) in the interval - 3 < x ≤ 1 , then f(x) = x + 1 , so
f(1) = 1 + 1 = 2
f(4) in the interval 1 < x ≤ 4 , then f(x) = 2x , so
f(4) = 2 × 4 = 8

Answer:
tan∠A = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
SOHCAHTOA
O= Opposite
H= Hypotenuse
A = Adjacent
So according to this the 3 is the opposite side and 5 is the hypotenuse.
So we need to find adjacent side for Tan.
For this we will use pythagorean theorem. [tex]a^{2} + b^{2} = c^{2}[/tex] c is the hypotenuse, b is the base.
We are sure that the hypotenuse is 5 but we dont know which side is 3 but it wont matter we can put it in either a or b because it would be adjacent at the end as we already know the other 2.
[tex]3^{2} +b^{2} = 5^{2} \\9 + b^{2} = 25\\b^{2} = 16\\b^{2} = 4^{2} \\b = 4[/tex]
So the adjacent side 4. Now according to TOA tan∠A = [tex]\frac{3}{4}[/tex]

Solve for the perimeter of the figure below. Round your answer to the nearest hundredth. Show your work and explain the steps
you used to solve.
Answer:
18.87 units
Explanation:
the estimated distance from a to d is the same as a to b. we can find the length of the diagonal using pythagoras' theorem:
a² + b² = c²
√(2² + 3²) = 3.6056 (to 5s.f.)
now, we can use the same method to calculate the distance between d and c, as well as c and b:
√(3² + 5²) = 5.8310 (to 5s.f.)
adding these values, we will get:
(3.6056 + 5.8310) × 2 = 18.87 units (to the nearest hundredth)
i hope this helps! :D
