Question

a)x+90=360

b)6x+4x=360

c)3x+x+180=360

Answer 1

a)  x+ 90 = 360

x= 360 -90

x= 270º

b) 6x + 4x = 360

10 x = 360

x= 360/10

x= 36º

c) 3x + x + 180 = 360

4x = 360 - 180
4x = 180

x= 180/4

x= 45º

Answer 2

A)x + 90 = 360
    x = 360 - 90
    x = 270


B) 6x + 4x = 360
    10x = 360
    x = 360 / 10
    x = 36

C) 3x + x + 180 = 360
     4x = 360 - 180
     4x =  180 
     x= 180 / 4
     x = 45
