Answer:
b= 58°
Step-by-step 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°
