Question

Find the value of x.

Answer 1

X = 26°, Reason, Interior Angles of a triangle add up to 180°

Answer 2

x = 27

Explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

90 + x + 23 + x + 13 = 180, that is

126 + 2x = 180 ( subtract 126 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
