The whole thing has to equal 90 degrees. So the expression has to equal 40 degrees. The only number that satisfies the expression is 5. (5(5)+15)=40.

90-50=40 so with the 40 left we now subtract 15 from 40 to get 25, divide 25 by 5 to get x=5

Answer:

B ( 92 degrees)

Step-by-step explanation:

1. Find y

In order to find z, we need to find y.

All triangles add up to 180 degrees, so y would be

180 - (48 + 44) = 88

y is 88 degrees

2. Find z

So now we know y is 88, we can find z

The circle of all angles of y and z = 360 ( because full angle)

so our equation is:

(88 + z)2 = 360

Divide by 2

88 + z = 180

z = 92
