You have the following expression:

(2z - 3) + (5z - 6) = 180

in order to solvet the previous expression for z, proceed as follow:

(2z - 3) + (5z - 6) = 180 cancel out parenthesis

2z - 3 + 5z - 6 = 180 simplify like terms left side

7z - 9 = 180 add 9 both sides

7z = 180 + 9

7z = 189 divide by 7 both sides

z = 189/7

z = 27

Hence, the value of z is 27

Next, replace the values of z into the expression for the measureof angle M:

Hence, the measure of angle M is 129°
