Answer:
x = 16
Step-by-step explanation:
From the first statement, we can say that:
Angle A is equal to angle D,
Angle B is equal to and E.
Since measure of Angle B and E are given and they are equal, we equate them and solve for x.

Hence x = 16
Answer:
x
Step-by-step explanation:
Ok so what you need to do is first find the area of the circle using π r^2. So π12^2 or π144= 452.389342117 This is the area of the whole circle. To find the area of the sector you have to multiply the total area by 172/360 or 0.47777777777 This will get you 216.141574567 round as necessary but your answer is <span>216.141574567units^2</span>
<span> |-6| + 2|-4| - 3|6|
get rid of the absolute values so it's

do PEMDAS

Given the scores on a statewide standardized test are normally distributed
Mean = μ = 78
Standard deviation = σ = 3
Normalize the data using the z-score by using the following formula and chart:

Estimate the percentage of scores of the following cases:
(a) between 75 and 81
so, the z-score for the given numbers will be:

As shown, the percentage when (-1 < z < 1) = 68%
(b) above 87

The percentage when (z > 3) = 0.5%
(c) below 72

The percentage when (z < -2) = 0.5 + 2 = 2.5%
(d) between 75 and 84

The percentage when ( -1 < z < 2 ) = 68 + 13.5 = 81.5%
