Advanced Mathematics Primary 6 Angles

In the figure, two parallel lines are cut by a transversal. The angle marked p is 32° more than the angle marked q. The two angles are co-interior (sum to 180°). Find p.

A 180°
B 74°
C 106°
D 148°

Worked Solution

Step 1: Let q be the smaller angle. Then p = q + 32. Step 2: Co-interior angles sum to 180°: p + q = 180°. Step 3: Substitute: (q + 32) + q = 180 → 2q = 148 → q = 74°. Step 4: p = 74 + 32 = 106°. Answer: 106°

Correct answer: 106°
