Question

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

Answer 1

Given that,

x = 45°

y =?

z =?

u =?

z = x = 45°(Vertically opposite angle)

z + u = 180°(Linear pair)

45° = 180° – u

u = 135°

x + y = 180°(Linear pair)

45° = 180° – y

y = 135°

Therefore,

x = 45°, y = 135°, u = 135° and z = 45°
