Anyone know this I got stuck ?

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.

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.

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.

32 + 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 :)

Answer:

0.2

Step-by-step explanation:

[tex]\frac{7}{15}[/tex] x [tex]\frac{6}{14}[/tex] = 0.2

Answer:

The answer is B, P = 12(1.004)^t

A growth rate of 0.4% means you have to multiply by 1.004

B is the only answer with this number, so B is the correct choice.

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] )

Step-by-step explanation:

Answer:

Length = 2 feet

Width = 6 feet

Step-by-step explanation:

Let the length of a flower garden = l feet

And the width of the garden = w feet

Perimeter of the rectangular garden = 2(l + w)

16 = 2(l + w)

l + w = 8

l = 8 - w ---------(1)

Area of the rectangular garden = lw

12 = lw ---------(2)

By substituting the value of length in equation (2)

12 = (8 - w)w

12 = 8w - w²

w² - 8w + 12 = 0

w² - 6w - 2w + 12 = 0

w(w - 6) + 2(w - 6) = 0

(w + 2)(w - 6) = 0

w = -2, 6 feet

Since, width of the garden can't be negative.

Therefore, Width of the garden = 6 feet

From equation (1)

l = 2 feet

Therefore, length of the garden is 2 feet and width is 6 feet.

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

Answer:

21.

Step-by-step explanation:

An outlier is basically a data point that is just significantly different from other data values (way higher or way lower.)

However, you can see that most of the data points range in the 50-70 points, except the 21. Therefore, it is an outlier.

Answer:

The outlier will be 21.

Step-by-step explanation:

As we can see, most of the points are in the 50, 60, 70 range.

There are none in 30 nor 40.

21 is far away from the 50, 60, 70 range (where most points are), so therefore, it is an outlier.

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!

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)
