Solve for x= 4x+18°+5x°=90°
pishuonlain [190]

Answer: x = 8

<u>Step-by-step explanation:</u>

4x + 18  +  5x  =  90

9x + 18 = 90             <em>Added like terms</em>

9x = 72                    <em>Subtracted 18 from both sides</em>

x = 8                       <em>Divided both sides by 9</em>


BONUS: The sum of these two angles is 90°, which means these angle are complementary.
