Question

please answer step by step​

Answer 1

Answer:

Please mark me as a brainlist.

Step-by-step explanation:

a, solution;

 x + 75°+ 40° =180°  (∵ being traingle )

or, x+115° =180°

or, x = 180° - 115°

∴ x= 65°

b, solution;

x+ 90° + 36° = 180° (∵ being triangle)

or, x+ 126° = 180°

or, x= 180° -126°

∴x= 54°

c, solution;

x+x + 52° = 180° (∵being triangle)

or, 2x + 52° =180°

or, 2x= 180° - 52°

or, 2x= 128°

or, x= 128° / 2

∴ x=64°

d, solution;

x+ x+10 +( x-10) =180° (∵ being traingle)

or, x+ x+10+x-10 =180°

or, 3x =180°

or, x= 180°/3

∴x=60°

e, solution,

x+2x+25° + 2x-5° =180° (∵being traingle)

or, 5x+20° =180°

or, 5x= 180°-20°

or,5x=160

0r, x= 160°/5

∴ x= 32°
