Question

Please help does anyone know this

Answer 1

Answer:

70

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 2

Answer:

?+45=115° sum of two interior angle of the triangle is equal to the exterior angle

<XWY=115-45=70
