A. X = 18
B. X = 48
C. X = 82
D. X = 98

Answer:

65°

Step-by-step explanation:

First we find the sizes of the other two sides, as the bottom line is straight all angles on it must add up to 180 so:

180-105=75

So the first angle is 75°

180-140=40

So the second angle is 40°

Now as the angles of a triangle add up to 180 we can derive this equation:

75+40+x=180

and all we do is just subtract both sides by 75 and 40:

x=180-75-40

x=65

And 65 is our answer

Answer:

(7, - 5 ) and r = 2

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 7)² + (y + 5)² = 4 ← is in standard form

with centre = (h, k ) = (7, - 5 ) and r = [tex]\sqrt{4}[/tex] = 2

Answer:

5.3%

Step-by-step explanation:

The first step is to find the z score corresponding to $200.

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{200-144.05}{34.52}\approx 1.62[/tex]

The next step is to find the area under the standard normal curve to the right of z = 1.62.  Some graphing calculators can do this, and there are tables that will help, although many of those show areas to the left of a particular z-score.

Calculator (TI-83/84)

See the attached image.

The command uses 1 x 10^99 as "positive infinity" and calculates the area under the normal curve from 1.62 all the way to the right.

Table

See attached table.  This table shows areas to the left of a certain z-score.

Find the entry for 1.62 (it's on page 2 highlighted with a red box).  The table says the area to the left of 1.62 is 0.9474.

But the area under the entire curve is 1!

This important fact means that the area to the right of z = 1.62 is 1 - 0.9474 = 0.0536, about 5.3%

(To get the area to the right of z, subtract the area to the left of z from 1.)

Answer:

  D  2.14

Step-by-step explanation:

The lengths of interest are the hypotenuses of the respective triangles. We are given the angle and the opposite side, so the sine relation is of interest.

  Sin = Opposite/Hypotenuse

  sin(34°) = AC/AB   ⇒   AB = AC/sin(34°)

  sin(53°) = AC/AD   ⇒   AD = AC/sin(53°)

The desired difference in lengths is ...

  AB -AD = AC(1/sin(34°) -1/sin(53°)) = 4(1.78829 -1.25214) ≈ 2.1446

The difference in lengths is about 2.14 units.

Answer:

The complement of 73° is 17°

The supplement of 73° is 107°

Step-by-step explanation:

Two angles in a complementary are equal to 90°

∴ For complementary:

73° + x = 90°

x = 90°- 73°

∴ x =  17 °

Two angles in a supplementary are equal to 180°

∴ For supplementary:

73° + x = 180°

x = 180° - 73°

∴ x =  107°

Answer:

26° 26° 128°

77° 77° 26°

Step-by-step explanation:

So we have two scenarios here.

One of them is if the base angles are 26°.

If that's true, the other angle is 128°

The other scenario is the opposite.

This means the base angles are 77°

Step-by-step explanation:

pythagorean theorem will solve this so A^2 + B^2=C^2

we have a and c so you do c -a and square root it to get your answer

The height of the building is approximately 24.19 feet.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, place a 29-foot ladder against the top of a building and the bottom of the ladder is 16 feet from the bottom of the building.

So, hypotenuse of the triangle is 29 feet and base of the triangle is 16 feet.

Let h be the height of the building.

Now, 29²=16²+h²

841=256+h²

h²=841-256

h²=585

h=24.19 feet

Therefore, the height of the building is approximately 24.19 feet.

Step-by-step explanation:

Answer:

a) -1535.5

b) 0

Step-by-step explanation:

A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.

The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.

Putting the two together, we get 24.5 - 1560, which is -1535.5.

--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.

We plug in -1/3 where a is and -1 where b is. So:

-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.

The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.

-1/9 * 1  - 3(-1/27) * 1

= -1/9 + 1/9

= 0

Answer:

2.275%

Step-by-step explanation:

z = (x-μ)/σ, where

x is the raw score = 14.9 ft

μ is the population mean = 12.5 ft

σ is the population standard deviation = 1.2 ft

We are to find the percentage of the apple trees are taller than 14.9 ft,

This means x > 14.9, x greater than 14.9

Hence,

z = (14.9 - 12.5)/1.2

z = 2

Probability value from Z-Table:

P(x<14.9) = 0.97725

P(x>14.9) = 1 - P(x<14.9) = 0.02275

Converting to Percentage

= 0.02275 × 100

= 2.275%

Therefore, the percentage of the apple trees that are taller than 14.9 ft is 2.275%

23.82° is derived as the value of x according to nthe diagram shown.

This is referred to the angle from the horizontal upward area to an object.It is measured in degrees.

36 = 225/y

y = 225/tan 36

  = 309.686.

tan(x) = 225 / y+200

x = tan -1 (225/309.686)

x = 23.82
