Question

The measures of two angles of a triangle are given. Find the measure of the third angle.

$85°$$,45°$

Answer 1

Find the measure of the third angle:

The two angles of the triangles are of $85°$and $45°$.

Let the third angle be $x$.

We know that from angle sum property of triangle;

The sum of all interior angles of triangle is $180°$.

$\Rightarrow$$x+85°+45°=180°$

$\Rightarrow$ $x=180°-130°$

$\Rightarrow$ $x=50°$

Thus, the required third angle will be $50°$.
