Question

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answer 1

x=3
……………………………………..

Answer 2

x = 14°

Explanation:

The sum of the angles of a triangle is 180°

.

Let's make an equation according to this:

47° + 103° + (3x - 12)° = 180°

150° + 3x - 12° = 180°

3x = 180° + 12° - 150°

3x = 42° / : 3

x = 14°
