Question

Angles on a line add up to 180. So what is x?

Answer 1

x=121

Explanation:

• 360_304=56
• 180_115=65
• 65+56=121
• x=121

Answer 2

x = 121°

Explanation:

180 - 115 = 65°

The angle beside 115° is 65°.

A full circle is 360° so

360 - 304 = 56°

Add the two angles

65 + 56 = 121°

Subtract it to 180° to find the other angle

180 - 121 = 59°

Now subtract again to 180° to find the angle in the other side

180 - 59 = 121°
