You would find this as the only thing present was the isosceles triangle.

A + 2B = 180
A = 46
46 + 2B = 180
2B = 134

Now here's the tricky part. Just what are you being asked for? If it is both of the acute angles then the answer is 134°

If it is just one of them then the answer is 134/2 = 67°
I would take 67 because of the an. But what you have written is plural,which would make the answer 134.

The measure of an acute base is 67.

What is isosceles trapezoid?

A  trapezoid with its two nonparallel sides equal.

Given:

angle = 46

consider

<A + <B+ <C = 180

<A + 2 <B= 180

A = 46

46 + 2B = 180

2B = 134

B= 67.

Hence, the measure of acute angle is 67.
