Question

Two sides in a triangle each have a length of 4 feet. If the angle opposite the base of the triangle is 30°, what are the measures of the three angles of the triangle?

Answer 1

30 degrees

90 degrees

60 degrees

Explanation:

If two of the sides are four, we know that the triangle is a right triangle so one angle is 90 degrees. if the other angle is 30, you can add them. 30+90=120. Then subtract it by 180 because all angles in a triangle add up to 180. 180-120=60.
