Answer:
x = 31°
Step-by-step explanation:
the triangle on the right is isosceles because two sides are equal, which means the two base angles are equal
if we subtract 56 from 180, then divide by 2 we have each base angle equal to 62°
the base angle, adjacent to the obtuse angle in the triangle on the right, is supplemental to the obtuse angle, so 180 - 62 = 118
the triangle on the right is isosceles also because two sides are equal, which means the two other angles are equal
if we subtract 118 from 180 we get 62, so each of the other two angles are 32°
