Find the angles of a triangle that are in ratio $$2 : 2 : 5$$.


SOLUTION
Given angles are in ratio $$2:2:5$$

Let the angles be $$2x, 2x$$ and $$5x$$

sum of angles$$=180^o$$

$$2x+2x+5x=180^o$$

$$9x=180^o$$

$$\Rightarrow x=20^o$$

$$\therefore$$ angles are $$(2x, 2x, 5x)$$

$$\Rightarrow (40^o, 40^o, 100^o)$$.
