Question

What is the Equation/how do you solve for this?

Answer 1

b= 58°

Explanation:

32° +b +90°= 180° (adj. ∠s on a str. line)

b +122°= 180°

b= 180° -122°

b= 58°

What is adj. ∠s on a str. line?

• an abbreviation for 'adjacent angles on a straight line'
• the sum of all the angles on a straight line is 180°

Where did the 90° come from?

• The small square in the question denotes that the angle is a right angle, or 90°
