Question

Find the value of x.

Please help and can somebody tell me how to find x?

Answer 1

x = 75°

Explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

78° + 27° + x° = 180°

Add like terms

105 + x = 180

105 + x - 105 = 180 - 105 (substraction property of equality)

x = 75°
