<h3>
Answer: sqrt(3)</h3>
========================================================
Work Shown:
The tangent ratio involves the opposite over adjacent.
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = sqrt(75)/5
tan(A) = ( 5*sqrt(3) )/5 .... see the section below
tan(A) = sqrt(3)
---------------------------
sqrt(75) = sqrt(25*3)
sqrt(75) = sqrt(25)*sqrt(3)
sqrt(75) = 5*sqrt(3)
$1.50
I hope this is what you need
I don't know about the circle, but from the way it looks, you can use pythagorean theorem (A^2+B^2=C^2). angle E would be the Right Angle making 65=C or in other words, the hypotenuse, with 60 and Line ED being the legs (it doesn't matter which is A and which is B) leaving the equation
60^2+B^2=65^2 and solve from there. (if you need help solving, leave a comment and i will walk you through it in the comments)
The pyhtagorean states that to find c, use the eqaution,
.
Substitute 1 for a and 20 for b;
c^2=1+400
c^2=401
c=
which is about 20.02
Hope this helps.
Based on the problem Carl will complete...
1/6 of the job per minute.
Fred will complete 1/8 of the job per minute.
Together they will complete... 1/6+1/8 of the job per minute.
That would be 7/24.
How long will that take?
1/(7/24)=24/7=3 3/7
It will take 3 and 3/7 minutes to finish washing the car.
