Question

In ∆PQR, angle P = 70° angle Q=75° then find R​

Answer 1

Answer:

angle R = 35°

Step-by-step explanation:

in ∆ PQR

Angle P+ Angle Q + Angle R = 180° (angle sum property of ∆)

70+ 75+ angle R = 180°

145° + angle R = 180°

angle R = 180- 145

angle R = 35°

Answer 2

ANSWER - 35°

STEP BY STEP EXPLANATION -

ANGLE P + ANGLE Q + ANGLE R = 180° ( ANGLE DUM PROPERTY)

70° + 75° + ANGLE R = 180°

145° + ANGLE R = 180°

ANGLE R = 180° - 145°

ANGLE R = 35°
