Question

Angle 1 and angle 2 are supplementary angles, angle 1 and angle 3 are vertical angles. m<2=67 degrees. find m< 3

Answer 1

113 degrees?

Answer 2

m<3 would be 113 because if <1 and <2 are supplementary angles and <2 is 67 degrees, then subtract that from 180 which would be 113, but they are looking for <3 which is equal to <1 because they are vertical angles, so your final answer will be m<3=113 degrees

Answer 3

yes thats correct PoohBear

Answer 4

vertical angles are equal
so <1 = <3
supplementary angles add up to 180
so <1+<2=180
yes correct :)
