Find the measure of x, then find the measure of each angle​
stepladder [879]

First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:

180° = 90° + (x/2) + (7x - 90°)

180° = x/2 + 7x

180° = x *(1/2 + 7)

180° = x*(15/2)

2/15 * 180° = x

24 = x

Angle A:

A= x/2

A = 24/2

A = 12°

Angle B:

B = 7x

B = 7*24

B = 168°

The two bottom angles are both worth 90°.

Match each number with its place in order from smallest (1st) to largest (6th).

90 would be the largest then 59,48, -56, -80, and leaving -84 to be the smallest

Answer:

First question: 42cm^2

Second question:

whole figure: 150 cm^2

blue part: 96cm^2

white part:54cm^2

Step-by-step explanation:

Lets do math:

look you gave me alot to do but lets go:

Question 1:

lets find the area of the whole rectangle without the parts taken away.

6*10-60

lets put that away for a little bit and move onto the empty space that we have to take away from the rectangle to get this shape.

im now going to subtract 2 from 10 to get 8. I did this to find out the a length

8*3=24

18 is the area of the shape that we have to subtract from the big rectangle

lets now take out the area we put away for a little while.

60-18=42

so 42 is the area of the first shape.

Question #2:

This problem needs multiple answers so lets get started.

first we need to find the area of the big rectangle.

10*15=150

lets put that away for a little bit.

now lets find the area of the little rectangle

6*9=54

to find the blue we have to subtract 54 from 150 which is 96

so now we have this:

area of the whole figure:150

area of the shaded rectangle inside (white): 54

area of the shaded rectangle (blue): 96

phew that was a lot of typing

the end

Answer:

119.2

Step-by-step explanation:

Given the following :

Mean (m) = 100 years

Standard deviation (sd) = 15 years

closest to the age of a Galápagos Islands giant tortoise at the 90th percentile of the

distribution?

Obtain the Zscore for 90th percentile (0.90) on the z table = 1.28

Zscore = (X - mean) / standard deviation

1.28 = (X - 100) / 15

1.28 × 15 = X - 100

19.2 = X - 100

19.2 + 100 = X

X = 119.2
