Question

. In triangle PQR, P=64, Q= 37, find the value of exterior angle at R​

Answer 1

Answer:

∠θ+∠Q+∠R=180

∘

(∵PQR is a triangle )

⇒∠Q+∠R=180

∘

−20

∘

⇒

∠Q+∠R=∠P

Answer 2

Answer:

In triangle PQR,

P=69,

Q=37

By using of exterior angle thearom,

Angle P+Angle Q=exterior angle at R

69+37 =exterior angle at R

Angle 106 =exterior angle at R
