Answer:
Angles 1 and 2 are 115 degrees. Angles 3 and 4 are 65 degrees.
Explanation:
7x - 4 + 3x + 14 = 180 (angles 1 and 3 form a straight line so they add to 180 degrees)
10x + 10 = 180
10x = 170
x = 17
m<1 = 7(17) - 4 = 115
m<3 = 3(17) + 14 = 65
Opposite angles are equivalent so m<2 = 115 and m<4 = 65.
