In a right triangle find the length of the side not given. b=1, c=sqrt10, a

Question

need help

Answer 1

In a right triangle

given sides are

b=1 , c= root 10 ,a=?


a= root { 1^2 +(root 10)^2 }

= square root of 11

Because 1^2=1 & root 10^2=10

Answer 2

So the third side is sqrt 11. I just want to make sure that I understand how to work this.

Answer 3

In a right triangle find the length of the side not given. b = 1, c = sqrt10, a = ?

If the two sides are a and b and the hypotensuse = c,

a^2 + b^2 = c^2

a^2 + 1^2 = 10

a^2 = 10 - 1 = 9 makaing a = sqrt9 = 3.

Answer 4

Thanks for clearing that up
