Mathematics

Mark the correct alternative of the following.
If the measures of the angles of a triangle are $$(2x)^o, (3x-5)^o$$ and $$(4x-13)^o$$. Then the value of x is?


ANSWER

$$22$$


SOLUTION
Sum of angles of triangles $$=180^0$$
$$2x+3x-5+4x-13=180^0$$
$$9x-18=180^0$$
$$9x=198^0$$
$$\boxed{x=22^0}$$
