Answer:
a=19
Step-by-step explanation:
First we have to distribute the parenthesis; multiply (a+5) by 1/3
8=1/3*a+1/3*5
Now we just solve the equation regularly
8=1/3a+5/3
8-5/3=1/3a
6 1/3=1/3a
a=19
General formula for circles at the origin is x^2+y^2=R^2 where R is the radius.So R^2=4225. Solve for R.
X= 18
