Answer:
Where is the number??????
Solving for y means to get that variable on one side of the equation and everything else needs to be on the opposite side of y.
We also know x is equal to 28. So, we can replace x with 28.
Now the equation will look something like 28 + 3y = 28
Now let us solve it.
28 + 3y = 28
First, subtract 28 from each side of the equation.
(28 + 3y) - 28 = 28 - 28 =
3y = 0
Now divide each side by 3.
3y / 3 = 0 / 3
y = 0/3
If a fraction has a numerator of 0, that means it's 0.
So, y is equal to 0.
Answer:
Angle A = 32
Angle B = 96
Angle C = 52
Step-by-step explanation:
180 - 52 = 128
128 / 4 = 32
Angle A = 32
Angle B = 3 x 32 = 96
Angle C = 52
Check:
32 + (3 x 32) + 52 = 180
