Which equation can be used to find the unknown length, b, in this triangle?
A right triangle has a side with length 4 inches and hypotenuse with length 5 inches. The other side is labeled b.
4 squared + b squared = 5 squared
4 squared minus b squared = 5 squared
5 squared + 4 squared = b squared
5 squared + b squared = 4 squared

The equation that can be used to find the unknown length, b, in this triangle is b^2 = 5^2 - 4^2

What is pythagoras theorem?

The square of the hypotenuse is equal to the sum of the square of the other two sides

Let the right triangle has a side with a length of 4 inches and a hypotenuse with a length of 5inches.

The unknown side is calculated as shown:

b^2 = h^2 - o^2

b^2 = 5^2 - 4^2

Hence the equation that can be used to find the unknown length, b, in this triangle is b^2 = 5^2 - 4^2
