Because a squared + b squared = c squared, and we know that the hypotenuse is c, we can turn the equation into 9^2 - 4^2= the other leg of the triangle. This equation is equivalent to 81 - 16 = 65. Then, you have to find the square root of 65 to get the other leg which is 8.06.
Answer:
Step-by-step explanation:
Pythagorean theorem,
leg ² + leg² = hypotenuse²
leg² + 4² = 9²
leg² + 16 = 81
leg² = 81 - 16
leg² = 65
leg = √65
leg = 8.06 units
