Answer 1

Answer:

in Q 8.

angle x is vertically opposite to 30°

n vertically opposite angles are equal

thus x= 30°

angle 30° and angle y form linear pair

n their sum will be 180°

so, 30°+y=180°

y= 180-30

y=150°

Q9.

x/4+9=5

(x+36)/9=5

x+36= 5×4

x= 20-36

x= - 16

thus x= -16 (-16/4+9=5)
