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°
