Question

in ∆PQR if <p=65° and <Q=50° then find R
​

Answer 1

Answer:

In ∆PQR if ∠P=65° and ∠Q=50° then ∠R=65°.

Step-by-step explanation:

Given: In ∆PQR

∠P=65° and ∠Q=50°

Find ∠R = ?

The sum of angles of a triangle is 180°.

∠P + ∠Q + ∠R= 180°

65°  + 50°  + ∠R= 180°

115°  + ∠R= 180°

∠R= 180° - 115°

∠R= 65°

So, measure of angle R is 65°
