Question

Question 3:
a.
Find x, y and z in the following figure:
250°
X
4
z+
120°

Answer 1

Answer:

The value of X = 50° {Alternate interior angle}

and,

value of y = 180°–120° = 60°

Then,

X+Y+Z = 360° {COMPLETE ANGLE}

Z = 360° –(50°+60°)

Z = 360°–110°

Z = 250°

Thus, value of X = 50° ,Y = 60° , Z = 250°

Answer 2

x=50 (alternate interior angles)
y+120=180 ( co-interior angles on the
same side of transversal)
y=180-120
y=60
x+y+z=360 (angle around a point)
50+60+z=360
110+z=360
z=360-110
z=250
Therefore, x=50,y=60 and z=250
