Equation in point slope form is given by y - y1 = m(x - x1); where m = (y2 - y1)/(x2 - x1).
y - 0 = (6 - 0)/(2 - 4) (x - 4)
y = 6/-2 (x - 4)
y = -3(x - 4)
Answer:
1,2,3,
Step-by-step explanation:
I GOT THE ANSWER WRONG AND IT TOLD ME THE CORRECT ANSWER
Get x to one side
So minus 90 from each side
-90÷-3=30
Answer: x=30
1. Use the Pythagoras theorem
13^2 = x^2 + 5^2
solve for x and youll get the height of the roof.
2. let x = length of the rpoe)-
x^2 = 9^2 + 12^2
3. Pythagoras again
20^2 = x^2 + 12^2
