Angle W:
180 = 90 + 57 + W
180 = 147 + W
W = 33 degrees
Using trigonometry functions to find the side lengths. (SOH CAH TOA)
Side XZ:
cos(57) = XZ / 18
XZ = cos(57) x 18
XZ = 9.8 units
Side XW:
sin(57) = XW / 18
XW = sin(57) x 18
XW = 15.1 units
Hope this helps!! :)

The answer of -30+10 is -20
-30+10=-20
Answer:
A) 1
Step-by-step explanation:
To solve, just plug in the numbers to the equation for x until both sides are equal to each other.
Plug in 1:
2(1 + x) = x + 3
Let x = 1:
2(1 + 1) = 1 + 3
Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:
2(1 + 1) = 1 + 3
2(2) = 4
4 = 4 (True)
A) 1 is your answer.
