The slope of the given line is -4/5. The line perpendicular to that line will have a slope that is the opposite reciprocal. In other words, the perpendicular slope will be 5/4. If it passes through (4, 12), we have an x and a y value to use in y=mx+b. y is 12, x is 4, and we have a slope of 5/4. Filling in accordingly:
and 12 = 5 + b. So b = 7. Rewriting with our new slope and b value,
. And there you go!

Answer:
4 is your value for m.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Do the opposite of PEMDAS.
First, add 5 & m to both sides:
2m (+ m) - 5 (+ 5) = - m (+ m) + 7 (+ 5)
2m + m = 7 + 5
Simplify. Combine like terms:
3m = 12
Isolate the variable, m. Divide 3 from both sides:
(3m)/3 = (12)/3
m = 12/3
m = 4
m = 4 is your answer.

Answer:
Step-by-step explanation:
Let the complement = x
Let the angle = 5*x
x + 5x = 90
6x = 90
x = 90/6
x = 15
So the complement = 15
The angle itself is 5*15 = 75
