Answer:

Step-by-step explanation:
The expression that we have in this problem is

First of all, we proceed by evaluating the power of the term in the brackets. We apply the rule:

So

Moreover, we have

Therefore,

So now the expression is

Now we apply the following rule:

So we have

Therefore, our expression becomes:

A. X=81
B. Y=99
C. Z=129
A triangle equals 180 degrees so all the numbers inside the triangle must add up to 180. Therefore you do 48+51-180 to give you x. Then subtract the number you got for x from 180 to find y and subtract 51 from 180 to find Z
Add them all around the top pointing down
Answer:
x=40
