Question

Finding the size of angle x on a straight line. 2 of the angles are 29 degree and 82 degrees

Answer 1

Answer:

x = 111°

Step-by-step explanation:

We know that angles in a triangle add up to 180°

Step 1: Find angle supplementary to x

82 + 29 + x = 180

111 + x = 180

x = 69°

Step 2: Find angle x

Both the angles are supplementary, meaning they add up to 180°.

x + 69 = 180

x = 111°
