Question

In triangle POR, Angle Q = 25° and angle R=65". Then find the value of angle P​

Answer 1

Answer:

By using the theorem,If two sides of a triangle are equal then the opposite angles to the sides are equal.

⇒ If PQ=PR then ∠Q=∠R

In △PQR,

⇒∠P+∠Q+∠R=180

∘

⇒∠P+∠Q+∠R=180

∘

since ∠Q=∠R=65

∘

(given)

⇒∠P+2×65

∘

=180

∘

⇒∠P=180

∘

−130

∘

=50

∘

∴∠P=50

Answer 2

sum of the angles of a triangle is 180

so,

angleQ + angle R +angle P = 180

25+65+P=180

90+P = 180

P = 180-90

P=90
