Answer:
The equation of the line is:

Step-by-step explanation:
A line perpendicular to the given one is going to have a slope equal to the opposite of the reciprocal of 1/4. That is the slope of the new line will be "-4".
Now we write the point-slope form for a line using the info provided of slope -4 and point (5, -4):

Answer:
243
Step-by-step explanation:
Simplify
27^2 / 3
729 divided by 3
= 243
Sin = opposite/hypothenuse
Given opposite = 16
Hypothenuse = ?
Use Pythagorean theorem to find hypothenuse
12^2 + 16^2 = h^2
144 + 256 = h^2
h^2 = 400, h = 20
You know hypothenuse is 20
Opposite/hypothenuse
Solution: 16/20
Simplify if you need to (4/5)
