# Triangle ABC is isosceles with vertex angle A is 30 degrees. Find the measure of each base angle. Solve please? Thanks!

75 degrees...

#### Explanation:

the total of the 3 angles in any triangle is always 180 deg.

So, the 2 base angles add up to 150, since 150 + 30 = 180.

The 2 base angles are equal, since we're told that it's an isosceles triangle.

150/2 = 75 degrees.

GOOD LUCK
