Question

In triangle PQR,angle P=70°,angle Q=65° then find angle R​

Answer 1

Answer:

Angle Sum Property :-

• The sum of all the interior angles of a triangle is equal to 180°.

Given :-

• angle P = 70°
• angle Q = 65°

To Find :-

• angle R

Solution :-

• angle R = 180° - ( 70° + 65° )
• angle R = 180° - 135°
• angle R = 45°

Therefore, angle R is equal to 45°.

Answer 2

Answer:

Step-by-step explanation:

In ΔPQR , ∠ P=70° , ∠Q=65°

We have to find ∠R

We know that sum of all interior angles of a triangle is 180°

So,  ∠P + ∠Q + ∠R = 180°

∴70 + 65 + ∠R = 180°

∴ 135° + ∠R = 180°

∴ ∠R = 180 - 135 = 45°

Ans : Measure of ∠R = 45°
