Question

find the measure of the missing angles.
answer attempt 2 out of 2
b =
°
c =
°

Explanation:

Step1: Find angle b

Angle b and 109° are supplementary (form a straight line).
$b = 180^\circ - 109^\circ = 71^\circ$

Step2: Find angle c

Angle c and 109° are vertical angles (equal).
$c = 109^\circ$

Answer:

b = 71
c = 109
