The largest angle of a triangle exceeds ten times the smallest angle by 10o. The third angle is equal by 60o. Find the size of the largest angle.

  

Answers


John
Let smallest angle be x

Largest angle is 10x + 10

therefore x + 10x + 10 + 60 = 180o

11x = 110o; x = 10

Largest angle is (10x + 10)

= (10 x 5.5 + 10) = 100 + 10

= 110o
