1.

a) Supplementary.

b) Supplementary.

c) Equal.

d) Equal.

e) Supplementary.

f) Supplementary.

2. a) 360°

b) opposite , 180° for a pair and 360° for 2 pairs.

c) straight line, 180°

3) angle 1 and angle 4 are pair of vertical angles summing upto 180°

4x + 5 + 3x + 11 = 180°

7x + 16 = 180°

x = 23.43°.

4) angle 3 and angle 4 are supplementary angles summing upto 180°

6x + 10 + 2x + 50 = 180°

8x + 60 = 180°

x = 15°

angle 3, 6x + 10

6(15) + 10 = 100°

m<3 = 100°

m<2 = m<3 - equal angles.

then, m<2 = 100°
