Number 1
<h2><em>
Definitions </em></h2>
<em>________________</em>
Supplementary - <em>either of two angles whose sum is 180°.</em>
Complementary - <em>either of two angles whose sum is 90°.</em>
<em>________________</em>
<em>Since we know that supplementary angles are angles that add up to 180° we can make an equation</em>
<h3>Let's phrase ∠B as x and substitute ∠A as 65°</h3>

Number 2
<em>Since we know that complementary angles are angles that add up to 90° we can make an equation</em>
<h3>Let's phrase ∠B as x and substitute ∠A as 65°</h3>
<em>________________</em>
