Answer:
do you mean 50/360? if 50/360 it is 50 degrees
if 50/350 it is about 50/350*360 = 51.429 degrees
120 = 1/2b + b + b
120 = 1/2b + 2b
120 = 2.5b
÷2.5 ÷2.5
48 = b <— that is the length of one of the congruent sides
to find the base multiply by 1/2 and you get 24.
THE ANSWER IS… B!

Two angles are supplementary when they <span>add up to 180 degrees.
x = angle
19x-60 = </span><span>supplement angle
x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12</span>° ← answer
