Question

In the given figure, triangle PQR is an isosceles triangle in which PQ=PR and angle Q=70° , Find angle P​

Answer 1

Answer:

Hope it helps ya mate :)

Step-by-step explanation:

∠P + ∠Q + ∠R = 180°

∠P + 70 + 70 = 180

∠P + 140 = 180

∠P = 180 - 140

∠P = 40°

Answer 2

Answer:

∠P=40°

Step-by-step explanation:

In ΔPQR

1)∠PQR=70°         ⇒Given

2)PQ=PR             ⇒Given

3)∠PQR=∠PRQ=70°  ⇒∠s opp. to equal sides are equal

4)∠PQR+∠PRQ+∠QPR=180°    ⇒ Angle sum prop of a triangle

⇒70°+70°+∠QPR=180°

⇒∠QPR=180°-(70°+70°)

⇒∠QPR=40°
