Two angles of a triangle are the same size. The third angle is 12 degrees
smaller than the first angle. Find the
meone the ongles

Let the measure of the first angle be = x

Let the measure of the second angle = x

Then , the measure of the third angle = x - 12

Let us find the value of all of these angles using the angle sum property .

Sum of all angles inside a triangle = 180°

∴ The measure of the first angle = 64° , the measure of the second angle = 64° and the measure of the third angle = 52° .
