Answer:
∠CDF= 70°
Step-by-step explanation:
there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.
First, I'd like to find ∠ADB.
- 85°+70°= 155°
- 180°-155°= 25°
- ∠ADB= 25°
Second, add all the angles together.
- 70°+50°+60°+85°+25°= 290°
- 360°-290°= 70°

Answer:
Step-by-step explanation:
The roots are really just what x is when the equation is equal to zero. So, an equation with these roots would look like this:
(x+3)(x-4/5)=y
however, this is not standard form. To get standard form we will need to expand the equation using FOIL.
x^2+3x-4x/5-12/5=
x^2+11x/5-12/5
and that would be your answer.
This stuff is a bit tricky and it get annoying with those pesky fractions. If you have any questions just comment.
