Answer:
Step-by-step explanation:
To find a line perpendicular to 2x - 5y = 20, we need to find the slope of the line. To get the slope, we can solve for y, and get the equation in the form of y=mx + b
So I will solve for y:
So we know the slope is 2/5
The slope of a perpendicular line is the oposite reciprocal of original line. So the oposite reciprocal of 2/5 is -5/2. That will be our new slope
Now that we know the slope we can use the point slope formula to find an equation, then solve for y.
y-y₁=m(x-x₁)
y-4 = -5/2(x+ 1/2))
y= -5/2x + 11/4
A) The roof would be horizontal
b) The roof would be vertical
c) The roof rises 5 feet
d) The peak is 15 feet from the front
e) Pitch = slope = rise / run
Pitch = 5/15 = 1/3
Answer:
A. 
Step-by-step explanation:
Hi there!
We are given right triangle PQR, with PR=5, RQ=12, and PQ=13
We want to find the value of sin(Q)
Let's first recall that sine is 
In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse
So that means that sin(Q) would be 
Substituting the values of PR and PQ gives sin(Q) as , which is A
Hope this helps!
The answer is 666 because I’m good at math
Answer:
B.
Step-by-step explanation: The answer is b because 65.04 is the answer we get from finding the difference of those irregular triangles and the circle.
P.S. They must be done seperately.
