Question

label the missing angle measures. explain how you arrived at your answer. your answer this is a required question

Explanation:

Step1: Find angle c

$c = 180^\circ - 55^\circ - 40^\circ = 85^\circ$

Step2: Find angle a

$a = 55^\circ$ (corresponding angles, parallel lines)

Step3: Find angle b

$b = 180^\circ - a - c = 180^\circ - 55^\circ - 85^\circ = 40^\circ$

Answer:

$a = 55^\circ$, $b = 40^\circ$, $c = 85^\circ$
