Question

can anyone help me doing this please​

Answer 1

Step-by-step explanation:

(a) 135° = 60° + x (Exterior angle property)

x = 135° - 60°

x = 75°

(b) 120° + PQR = 180° (Linear pair)

PQR = 180° - 120°

PQR = 60°

Similarly,

PRQ = 70°

Now,

PRQ + PQR + x = 180°

70° + 60° + x = 180°

130° + x = 180°

x = 180° - 130°

x = 50°

(c) 90° = 30° + x (Exterior angle property)

x = 90° - 30°

x = 60°

(d) 60° + QPR + 70° = 180° (Straight angle)

130° + QPR = 180°

QPR = 180° - 130°

QPR = 50°

Now,

x = QPR + 60 ° (Exterior angle property)

x = 50° + 60°

x = 110°
