Find the missing length. Round to the nearest tenth, if necessary.

Step-by-step explanation:

The given triangle is a right angle triangle. From the triangle,

The hypotenuse = 20ft

The length of one leg or adjacent side is 12 feet.

x represents the length of the other leg or opposite side.

To determine x, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = adjacent side² + opposite side²

Therefore

20² = 12² + x²

400 = 144 + x²

x² = 400 - 144

x² = 256

x = √256

x = 16 ft

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
