Answer:

m<1 = 50°

m<2 = 130°

m<3 = 50°

m<4 = 130°

m<5 = 50°

m<6 = 130°

m<7 = 50°

m<8 = 130°

Explanation:

Angle 4 & Angle 2 are congruent angles because they are diagonal from each other, this lets us set m<4 = m<2.

Then solve for x.

2x-10 = x+60

x-10 = 60

x = 70

Use x to find m<4 or m<2 (doesn't matter which b/c they are equal).

m<2 = (70)+60

m<2 = 130°

Angles 2, 4, 6 & 8 are congruent, so they will all have be 130°.

Angles 1 & 2 create a straight line (180°).

Find m<1 by subtracting 130° from 180°.

180-130 = 50

Angles 1, 3, 5 & 7 are also congruent, so they will all have be 50°.
