Question

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

Answer 1

Explanation:

the sum of all angles in a triangle is always 180°.

so,

180 = 84 + 41 + (2x + 15)

55 = 2x + 15

40 = 2x

x = 20

Answer 2

X = 20

Explanation:

2x + 15 = 180 - (84 + 41)

2x + 15 = 180 - 125

2x + 15 = 55

2x = 40

x = 20
