Question

find the value of the unknown exterior angle P in the following diagrams​

Answer 1

LET EXTERIOR ANGLE BE P

SUM OF INTERIOR OPPOSITE ANGLE = EXTERIOR ANGLE

SO , P = 70* + 45* = 115*

HOPE IT HELPS YOUU

Answer 2

Answer:

Angle A+Angle B+angleC=180°(angle sum property)

45°+70°+angleC=180°

115°+angle C=180°

angleC=180°-115°=65°

angleACX+AngleACB=180°(linear pair)

AngleACX+65°=180°

AngleACX=180°-65°=115°
