Answer:
Step-by-step explanation:
two angles are said to be supplementary if their sum is 180 degrees
Hence <1 + <2 = 180
Given
<1 = 28
Required
<2
Substitute into the formula
28+<2 =180
<2 = 180-28
<2= 152
Hence the measure of <2 is 152 degrees

Equation: 45 - 21 = <em>s</em>

<em>The second answer is 24.</em>
<em>You can check by adding 24 + 21 which is 45.</em>
