(a) – (q), (b) – (r), (c) – (s), (d) – (p)

(a) – (q)

x + x + 10 = 90

2x + 10 = 90

2x = 80

x = 40

x + 10 = 50^O

(b) – (r)

A + B + C =180

65 + B + B – 25 = 180

2B + 40 = 180

2B = 140

B = 70^O

(d) – (p)

A + B + C + D =360

2x + 3x + 5x + 40 = 360

10x + 40 = 360

10x = 320

X = 32^O

5x = 32 X 5 = 160^O
