Question

∠C and ​ ∠D ​ are vertical angles with m∠C=−3x+58 and m∠D=x−2 .



What is m∠D ?

Answer 1

Because these are vertical angles, they are equal to one another. So set them equal to one another to get -3x + 58 = x - 2. Solve for x to get that x = 15. Now sub 15 in for the x in the D expression: 15-2 = 13

Answer 2

Answer:

answer is 13 for sure
