Sign In
Use the Pythagorean Theorem.
3sqrt(13)yd
To find the missing side of the triangle, we will use the Pythagorean Theorem.
In the formula, a and b are the legs and c is the hypotenuse of a right triangle. We are given a triangle with a=6yd and b=9yd. Let's substitute these values into the formula.
a= 6, b= 9
Calculate power
Add terms
sqrt(LHS)=sqrt(RHS)
Rearrange equation
Split into factors
sqrt(a* b)=sqrt(a)*sqrt(b)
Calculate root
Since a negative side length does not make sense, we only need to consider positive solutions.
