Answer 1

Answer:

Q 1.

1/5 of 90 = 18

Q2.

2/3 of 180 = 120

Q.3

2x+60+3x-40 =180 [°.° Linear pairs angles]

= 5x + 20 = 180

= 5x = 180-20

= x =160/5=32

.°. x=32

Q4.

90+30+3y=180[°.°straight angle]

=120+3y=180

=3y=180-120

=y=60/3=20

.°.y=20

Q.5

i) supplement of 30°

=30+x=180°

=x=180-30

.°. x =150

iv) supplement of x°

=x+x=180

=2x=180

=x = 180/2

.°.x=90

v)

2/5 of 90=36

supplement of 36°

=36+x=180

=x=144

Q5.

4x+4+6x-4=180

10x=180

.°.x=18
