Question

plz friends solve the problem question no 10 and 11 plz plz plz plz plz help me

Answer 1

10.
(3x + 4) + (x - 2) = 90
3x + 4 + x -2 = 90
4x + 2 = 90
4x = 90 - 2
4x = 88
x = 22

11.
(2x + 10) + (3x + 5) = 180
2x + 10 + 3x + 5 = 180
5x + 15 = 180
5x = 180 - 15
5x = 165
x = 33

Hope the answer is correct...........

Answer 2

10. = 3x+4+x-2 = 90

= 4x+2 = 90. (complementry angle = 90)

= 4x = 88

= x = 22.

11. = 2x+10+3x+5 = 180

= 5x+15 = 180. (supplymentry angle = 180)

= 5x = 180-15 = 165

= x = 165/5 = 33.
