Question

If the angles of a triangles are in the ratio 11 : 13 : 12, then, what is the unit digit of the smallest angle?​

Answer 1

Answer:

Here is your answer =>

→ Given ratio=11:13:12

♦Let the angles be 11x, 13x, 12x

The sum of angles of a triangle =

→So, 11x+13x+12x=180

36x=180

x=180/36

x=5

therefore, the angles will be

11x=11x5=55 13x=13*5=65 12x=12*5=60

Smallest angle=55

Unit digit of smallest angle=5
