Question

Find the measures of angle B (questions 1-6)

Answer 1

1)

b = 42° (corresponding angles, parallel lines)

2)

b + 31 + 90 = 180 (sum of angles on a straight line=180)

b = 59°

3)

b + 34 = 180 (sum of angles on a straight line=180)

b = 146°

4)

b + 30 + 90 = 180 (sum of angles on a straight line=180)

b = 60°

5)

b + 35 + 90 = 180 (sum of angles on a straight line=180)

b = 55°

6)

b = 58° (alternate angles, parallel lines)
