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

70 degrees

Step-by-step 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

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
