Question

10) In the given figure below, find the value of x, Y and Z.
Y
2x + 15
3x - 10
Z
​

Answer 1

Answer:

X=25

Y=115

Z=115

Step-by-step explanation:

3x-10=2x+15 (Vertically opposite angles)

3x-2x=15+10

x=25

Y=Z (Vertically opposite angles)

3x-10+2x+15+Z+Y = 360

75 - 10 + 50 + 15 + Z + Y = 360

65+65 +Z + Y = 360

130 + Z + Z = 360 ( Turning Y into Z bcoz they're equal)

2Z = 360-130

2Z = 230

Z = 115
