Option A. if your using Plato!
Brainliest pls! thx! :)
Simplified that would be: 9(63+12+9) which if you add everything in the brackets, 9(84) which would be 9 times 84=756
First make an inequality to solve for x
(x + 45) + [(x + 45) - 30] + [2x + (x + 45)] = 180
x = 15
now plug x back into each equation and solve
first angle = 60°
second angle = 30°
third angle = 90°
2x+4y=6
4×1=4
2×1=2
4+2=6
x is 1 y is 1
6y-2z=-2
6×1=6
6-8=-2
8/2=4
z is 4
