Question

If mZ1 = (4x + 2)° and m/3 = (5x – 15)", what is the value of a?

Answer 1

Answer:

17

Step-by-step explanation:

angle one and angle three are equal to each other

so if you set the equations equal to each other

(4x+2)=( 5x-15)

move the 4x the right by subtracting it giving you 1x

then add 15 to 2 giving you 17

17=1x
