Question

(v).In fig PQR, PQ = PR and <Q = 65°. Then find R

​

Answer 1

Answer:

sum of all angles =180

Step-by-step explanation:

180 -65=115

so divide by two 115/2

57.5

Answer 2

Answer:

is this ur and? i am little confuse

Step-by-step explanation:

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
