a) n° + n°+ 42 = 180°

2n + 42 = 180

2n = 180 – 42

2n = 138

n = 138 /2

n° = 69°

_____o___o____

b) ( x+10) + x + ( x+5 ) = 180

x + 10 + x + x + 5 =180

3x + 15 =180

3x =180 – 15

3x = 165

x = 165 /3

x° = 55°

_____o___o___

c) 3q + q + q = 180

5q =180

q = 180/5

q=36°

___o___o____

d) m + 2m + ( m+10) = 180

m+2m+m+10=180

4m + 10=180

4m = 180 – 10

4m = 170

m=170 / 4

m = 42.5°

____o___o___

e) y + (y – 30 ) + 90° = 180°

y + y – 30 + 90 = 180

2y + 60 = 180

2y = 180 – 60

2y = 120

y = 120/2

y = 60°

____o___o____

f) ( t + 10.5 ) + 2t + 90 = 180

t + 10.5 + 2t +90=180

3t + 100.5 = 180

3t = 180 – 100.5

3t = 79.5

t = 79.5/3

t =26.5°

I hope I helped you^_^
