Question

(D) 30°
2.
In the adjoining figure line p line q.
Line t and line s are transversals.
Find measure of Zx and Zy
using the measures of angles given
in the figure.
​

Answer 1

Let p and q be parallel and t be the transversal

Therefore a= 40 corresponding angles

x+a =180. Angles in linear pair

X+40=180

X=180-40

X=140

Let p and q be parallel and s be the transversal

B=70. Vertically opposite angles

Y + B =180 angles on one side of transversal

Y+70= 180

Y=180-70

Y=110
