Question

In a triangle if angle P=79 degrees, angle Q=84 degrees find angle r

Answer 1

Answer :-

• Value of ∠R is 17°.

Given :-

• In a triangle, ∠P = 79°, ∠Q =84°

To Find :-

• ∠R

Solution :-

As we know that

→ Sum of all angles of a triangle is 180°

According to question :-

∠P + ∠Q + ∠R = 180°

→ 79° + 84° + ∠R = 180°

→ ∠R + 163° = 180°

→ ∠R = 180° - 163°

→ ∠R = 17°

Hence, the value of ∠R is 17°.
