Question

Type your answer into the box. X 30° Calculate the size of angle x. angle x =​

Answer 1

Answer:

x = 60°

Step-by-step explanation:

We know:

All triangles have internal angles that add up to 180°.

And

All right triangles have acute angles that up to 90°.

Therefore

x + 30° + 90° = 180°

x + 120° = 180°     |subtract 120° from both sides

x + 120° - 120° = 180° - 120°

x = 60°

or

x + 30° = 90°     |subtract 30° from both sides

x + 30° - 30° = 90° - 30°

x = 60°

Answer 2

Answer:

60°

Step-by-step explanation:

90°+30°=120°

180°_120°=60°
