Question

Solve for x in the diagram below.

Answer 1

X = 15

Step-by-step explanation:

We can tell that the two sides that show the degrees are equal because of the arc. We can set up a simple equation:

x + 45 = 60

x = 15

Answer 2

x = 15°

Step-by-step explanation:

The two marked angles are equal as they are vertically opposite angles.

∴ x + 45° = 60°

⇒ x = 60° - 45°

⇒ x = 15°
