angle 1 and 2 form a linear pair,angle 1 is 18 less than 5 times angle 2, what is angle 1

Answer 1

Linear pairs form 180

Let x=angle 2

Let 5x-18=angle 1

x+5x-18=180 Combine like terms

6x-18=180 Add 18 to both sides of the equation

6x-18+18=180+18 Simplify

6x=198 Divide both sides by 6

6x/6=198/6 Simplify

x=33

5x-18

5(33)-18 = 147° is the measurement of angle 1
