Question

Please help me i’m confused

Answer 1

x = 121°

Explanation:

The sun of all angles in a triangle is 180°

Since a circle has 360°, and 360 - 304 = 56, 56° is the top angle.

Since a striaght line has 180°, and 180 - 115 = 65, 65° is the left angle.

And since 180° - (56° + 65°) = 59°, 59° is the last angle.

But since x is on the outside, you have to subtract 180° from 59°, because they lie on a straight line. 180° - 59° = 121°.

Answer 2

x = 121°

Explanation:

The measures of two of the triangle's interior angles are:

180° - 115° = 65°

360° - 304° = 56°

We then have:

180° - (65° + 56°) = 180° - 121° = 59°

So x = 121°.
