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:

y = -2/3x-9

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -2/3x+b

We have a point we can substitute into the line

-5 = -2/3(-6)+b

Subtract 4 from each side

-5-4 =4+b-4

-9 =b

y = -2/3x-9
