Question

1. find the measure of ( e^circ ).

options: ( 159^circ ), ( 60^circ ), ( 21^circ ), ( 100.5^circ )

Explanation:

Step1: Find supplementary angle of 159°

$a^\circ = 180^\circ - 159^\circ = 21^\circ$

Step2: Identify corresponding angle to $a^\circ$

$e^\circ = a^\circ = 21^\circ$

Answer:

21° (Option: 21°)
