Question

i need answer with steps

Answer 1

Answer:

Step-by-step explanation:

a)x+130=180 linear pair

x=180-130=50

b)x+20+x=180  linear pair

2x+20=180

x=160/2

x=80

c)x=57    vertically opposite angle

d)x+18+x=180 linear pair

2x+18=180

x=162/2

x=81

e)x+x+x/2+90=360  sum of all angles is 360

2x+x/2+90=360

lcm=2

4x/2+x/2+90=360

5x/2+90=360

lcm of 2,1 =2

5x/2+180/2=360

5x+180=360x 2

5x=720-180

x=540/5=108

f) 2x+x= 180 linear pair

3x=180

x=180/3

x=60
