Question

Please help me ! not sure what to do. i also need to show steps

Answer 1

70 degrees

Explanation:

The exterior angle in a triangle is equal to the sum of the two opposite interior angles

So,

the two interior angles in the question are U and T while the exterior angle is V.

Using this,

U+T =V

U+50 = 120

(make U the subject of formula)

U = 120 - 50

U = 70 degrees
