Answer:
x = 51°, x = 91°
Explanation:
8) To find ∠ C, we subtract 180° - 86°, since they are on the same line.
∠ C = 94°
We also know that all angles in a triangle must add up to 180°, so
∠ C + ∠ D + ∠ E = 180°
94° + 35° + ∠ E = 180°
∠ E = 180° - 94° - 35°
∠ E = 51°
x = 51°
9) We know that all angles in a triangle add up to 180°, so
∠ U + ∠ V + ∠ W = 180°
∠ U + 62° + 29°= 180°
∠ U = 180° - 62° - 29°
∠ U = 89°
Since the x° angle is on the same line, we know that x° = 180° - 89°
x = 91°
