Step-by-step explanation:
By using formula of h^2=p^2+b^2
h=20
p=x
b=10
Now,
p=root h^2-b^2
x=root 20^2-10^2
x=root 400-100
x=root 300
x= 10root3
7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
