The largest interior angle in an isosceles trapezoid is 4 times the measure of the smallest interior angle. What is the measure, in degrees, of the smallest interior angle in the trapezoid?

Thank You in advance

These angles will sum to 180°

So

x + 4x = 180

5x = 180

x = 36° ⇒ measure of the smaller interior angle

never mind I got the answer, thank you though CPhill anyway

can you please help me with one of my other problems please
