Question

find the value of x.

Explanation:

Step1: Find the adjacent - interior angle to 124°

The adjacent - interior angle to the 124° exterior angle forms a linear - pair. So, it is 180 - 124=56°.

Step2: Use the angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. In the triangle, we have the angles x, 94°, and 56°. So, x + 94+56 = 180.
x=180-(94 + 56)
x=180 - 150
x = 30

Answer:

30
