Answer:
51 and 91
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
(8)
∠ GCD is an external angle of the triangle, so
35° + x = 86° ( subtract 35° from both sides )
x = 51°
(9)
∠ YUV is an external angle of the triangle, thus
x = 29° + 62° = 91°
