Question

In triangle PQR angle p =80 degree, angle Q=60 degree. find the greatest and the smallest side of the triangle
​

Answer 1

Answer:

Given,

Triangle PQR

P = 80

Q = 60

R = x

We know that all angles of a triangle is 180°

According to the question,

/P + /Q + /R = 180°

80 + 60 + x = 180

=> 140 + x = 180

=> x = 180 - 140

x = 40°

Greatest side or angle = /P = 80°

Smallest side or angle = /R = 40°
