Answer:
115 degrees
Step-by-step explanation:
We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.
Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees
Answer:
choice 3) W = 115 degrees
Step-by-step explanation:
all triangle interior angles add up to 180 degrees
180 = 45 + 70 + X
X = 65 degrees
Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)
W = 180 - 65 = 115 degrees
