Question

Use the diagram to find the measures of all angles, given that m<1= 76 degrees.

Answer 1

Answer:

m<1 = 76°

m<2 = 104°

m<3 = 76°

m<4 = 104°

Step-by-step explanation:

m<1 and m<3 are vertical angles so, these angles have the same measure of 76°. m<2 and m<4 are also vertical angles which have the same measure. To find m<2, use m<1. m<1 and m<2 are supplementary angles which add up to 180°. Subtract 180 from 76 which is 104.
