x=45
Explanation:
Statements | Reasons
90+x+5x=360 | A full rotation is 360 degrees.
90+6x=360 | I simplified (combined like terms).
6x=360-90 | I used subtraction property (minus 90 on both sides).
6x=270 | I simplified (combined like terms).
x=270/6 | I used division property (divided 6 on both sides).
x=45 | I simplified (performed the division).
