Answer: b
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Cos A = Adj/Hyp
Reference angle = <A
Adjacent side = 8 ft
Hypotenuse = √(8² + 5²) = √89 (pythagorean theorem)
Thus:
Rationalize
Answer:
a once again it is easy the answer is A
Step-by-step explanation:
You didn't give us a picture but I'll help you as best as I can.
First, convert the equation into the form y=mx+b:
15x-5y=30
-5y=-15x+30
Divide both sides by -5.
y=-3x-6
Below is a graph of that equation:
If we were to view the ramp from its side, the profile would resemble a right triangle with a 90 degree angle where the sofa meets the floor.
In this case, the two legs of the right triangle are 55 inches and 28 inches, and we looking for the length of the hypotenuse.
We can use Pythagorean Theorem which states:
where a and b are the legs, and c is the hypotenuse.
c = 61.717 inches
To the nearest tenth, the answer is 61.7 inches.
