Mathematics

Mark the correct alternative of the following.The angles of a triangle are in the ratio $2:3:7$. The measure of the largest angle is?

$105^o$

SOLUTION
Given the angles of a triangle are in the ratio $2:3:7$.
Let the angles of triangle be $2x,3x$ and $7x$.
Then according to the problem we get,
$2x+3x+7x=180^o$
or, $12x=180^o$
or, $x=15^o$.
Then the largest angle is $7\times 15^o=105^o$.
