Add them all up and if they add up to 180 then your side lengths are good
Hello from MrBillDoesMath!
Answer:
40
Discussion:
A diagram is always appreciated!
Assuming that
mAOC = mAOB + mBOC =>
108 = (3x + 4) + (8x - 28) => combine common terms
108 = (3x + 8x) + (4 - 28 ) =>
108 = 11x - 24 => add 24 to both sides
132 = 11x =>
x = 132/11 = 12
So mAOB = 3x + 4 = 3(12) + 4 = 36 + 4 = 40
Thank you,
MrB
The entire angle is a 90 degree angle.
Subtract the entire angle from what is given to find x.
90-28=62
x=62

none of the above im pretty sure

Answer:
![-\frac13](https://tex.z-dn.net/?f=-%5Cfrac13)
Step-by-step explanation:
Just the slope, so we can simply apply the definition, as variation in y over the variation in x
![m= \frac{\Delta y}{\Delta x} = \frac{1-4}{2-(-7)} = \frac {-3}{9} = -\frac13](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%20%3D%20%5Cfrac%7B1-4%7D%7B2-%28-7%29%7D%20%3D%20%5Cfrac%20%7B-3%7D%7B9%7D%20%3D%20-%5Cfrac13)
