Step-by-step explanation:
Hello There!
So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle
So basically
∠XYZ=∠WXY+∠XWY
so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)
115-45=70 so ∠XWY=70
Answer:
?+45=115° sum of two interior angle of the triangle is equal to the exterior angle
<XWY=115-45=70
