Q:
# ∠C and ∠D are vertical angles with m∠C=−3x+58 and m∠D=x−2 .What is m∠D ?

Accepted Solution

A:

vertical angles are equal

-3x + 58 = x - 2

-3x - x = -2 - 58

-4x = - 60

x = -60/-4

x = 15

m < D = x - 2....15 - 2 = 13 <====

m < C = -3x + 58....-3(15) + 58 = 13

-3x + 58 = x - 2

-3x - x = -2 - 58

-4x = - 60

x = -60/-4

x = 15

m < D = x - 2....15 - 2 = 13 <====

m < C = -3x + 58....-3(15) + 58 = 13
