Question

Construct a ΔPQR in which ∠P = 60° , ∠Q = 80° and PQ = 5 cm . Measure QR and PR.​

Answer 1

Step-by-step explanation:

1. A triangle consist the sum of the degree of the angles and it is 180°
2. it has given 2. degree=60°+80°+x=180°

Answer 2

Step-by-step explanation:

angle p + angleQ + angle R =180°

60°+30°+ angle R = 180°

angle R =90°

It is an right angled triangle
