Question

In Fig. 30, lines l1 and l2 intersect at O, forming angles as shown in the figure. If x = 45 o, find the values of y, z and u​

Answer 1

Answer:

Step-by-step explanation:

We know, The sum of all the angles on one side of a straight line is always 180 degrees

So, x°+u° = 180°, x°+y° =180° and y° + z° = 180°

Since x = 45°

from the above equations we get,

y = u= 135° and z = 45°

(NOTE: - Vertically opposite angles are same)
