Help! Can you help with finding the missing value?

x = 51°, x = 91°

Step-by-step 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°
