Question

11. The three angles of a triangle are in the ratio 1 : 2 : 1. Find all the angles of the triangle. Also
classify the triangle​

Answer 1

Answer: Let the common factor be x

1x+2x+1x=180                         (All angles of a triangle add upto 180)

4x=180

x=180/4

x=45

Therefore the angles are:

45, 45 x 2, 45

45, 90 and 45
