Answer:
x = 71º
Step-by-step explanation:
Using the equation a^2+b^2=c^2, you can figure out that the other leg is 64 units
Step-by-step explanation:
You can't use quadratic formula in this
We need to solve for R, This is really simple.
The original expression is:
R (r1 + r2) = r1r2
To solve for a certain variable, we need to get this variable alone on one side of the equation and equate it with the other side.
In the given expression, to get R alone on one side we have to eliminate (r1 + r2).
In order to do this, we will divide both sides by (r1 + r2).
Doing this, we get the solution as follows:
R = (r1r2) / (r1 + r2)
