Answer:
80 degree
Step-by-step explanation:
since the two sides are both 14, the lower right angle is also 50 degree.
The sum of all 3 angles inside a triangle is 180, so, 180 - 50 -50 = 80.
x = 80°
look at the side length, two of them are equal
so other unknown angle is also 50°
interior angles add up to 180
so 100 + x = 180
