Question

find angle x in the following figure x 108 52​

Answer 1

Step-by-step explanation:

We know that angle sum of a triangle = 180°

Thus, 30° + 90° + C = 180°

Or, 120° + C = 180°

Or, C = 180° – 120°

Or, C = 60°

Now,

y = 180° – C

⇒ y = 180° – 60° = 120°

z = 180° – 30° = 150°

x = 180° – 90° = 90°

∴ x + y + z = 90° + 120° + 150°

⇒ x + y + z = 360° Answer
