Question

In triangle PQR PQ=PR angle Q=70 degrer find angle P

Answer 1

In triangle PQR,
PQ = PR
therefore, It is an isosceles triangle.
So, angle Q = angle R = 70 degree.
then,
angle P + angle Q + angle R = 180.
angle P + 70 + 70 = 180.
angle P = 180 - 140
angle P = 40 degree.

Answer 2

Step-by-step explanation:

Given that PQ=PR then ∠R=∠Q=x

Given that PQ=PR then ∠R=∠Q=x∠P+∠Q+∠R=180∘

Given that PQ=PR then ∠R=∠Q=x∠P+∠Q+∠R=180∘x+x+40∘=180∘

Given that PQ=PR then ∠R=∠Q=x∠P+∠Q+∠R=180∘x+x+40∘=180∘x=70∘.

Given that PQ=PR then ∠R=∠Q=x∠P+∠Q+∠R=180∘x+x+40∘=180∘x=70∘.∠R=∠Q=70∘.
