Question

find the measure of the missing angles. answer attempt 1 out of 2 b = o c = o 89° c b

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. Angle $b$ and the $89^{\circ}$ angle are vertical angles, so $b = 89^{\circ}$.

Step2: Use linear - pair property

The sum of angles in a linear pair is $180^{\circ}$. Angle $c$ and the $89^{\circ}$ angle form a linear pair. So $c=180 - 89$.
$c = 91^{\circ}$

Answer:

$b = 89^{\circ}$
$c = 91^{\circ}$
