Question

Rini used a stick to draw a right triangle in the ground. The hypotenuse of her triangle is 24 inches and one of the legs is 12 inches. What is the length of the third side? Round to tenth if necessary.

Answer 1

Use the pythagorean theorem A² + B² = C²

A and B are legs and C is the hypotenuse

so- A² + 12² = 24² A² + 144 = 576
-144 -144

A² = 432 then you have to take the square root
of each side

so- A = √432 or aprox. 20.78
