Question The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is twice
the measure of the first angle. The third angle is 12 more than the second.
Let x, y, and z represent the measures of the first second, and third angles, respectively. Find the measures of the three
angles.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: 5100 just subtract
