Question

6. Lines I and m intersect at 0, forming angles
as shown in figure. If x = 45°, then values
of y,z and u are respectively
(a) 45° 135 135°​

Answer 1

Step-by-step explanation:

given,x= 45°

since vertical opposite angles are equal , therefore. z=x=45°

z and u are angles are a linear pair, therefore z+u=180°

solve,

z+u=180°

u=180°-z

u=180°-45°

u=135°

again x and y angles are linear pair

x+y=180°

y=180°-x

y=180°-45°

y=135°

Hence, y=135°

u=135°

z=45°
