DE+EF=DF
8x+2=x+9
8x-x=9-2
7x=7
x=7/7
x=1
DF=x+9
put the value of x
DF=1+9
DF=10
Answer:
y = 1/5x + 8
Step-by-step explanation:
The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, the slope of line j is 1/5. This is your current equation: y=1/5x + b. Plug in your coordinate to the equation, it should look like this: 9=1/5(5)+ b. 1/5 times 5 equals 1, so this is what it should look like: 9=1 + b. Subtract 1 from both sides to get 8 = b. Go back to your original equation and plug in 8 to b. This is your final equation: y = 1/5x + 8. Hope this helped!

Answer:
Step-by-step explanation:
<u>Measure B and C:</u>
<u>Subtract 110° - 40°:</u>
- 110° - 40°
- = 110 - 0
- = 110 - 40
- = 70°
<u>The measure of ∠BFC is 70°.</u>
