Answer:

solution for x,y,and z.

x+76= 180

x = 180-76

x = 104°

y + x = 180

y + 104 = 180

y = 180 - 104

y = 76°

z + 76 = 180

z = 180 -76

z = 104°

solution for x and y

(3x+5) + ( x+15) = 180

3x + 5 + x + 15 = 180

4x + 20 = 180

4x = 180 -20

4x/4 = 160/4

x = 40

(y+20) + (4y-15) = 180

y + 20 + 4y - 15 = 180

5y + 5 = 180

5y = 180 - 5

5y/5 = 175/5

y = 35

and find the angles measure

for: 3x + 5

= 3(40) + 5

= 120 + 5

= 125°

for: x + 15

= 40 + 15

= 55°

for: y + 20

= 35 + 20

= 55°

for: 4y - 15

= 4(35) - 15

= 140 - 15

= 125 °
