find ∠P Don't spam​

Answer 1

Answer:

∠P=50 °

Step-by-step explanation:

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 °
