Question

if a represents the hypotenuse of this right triangle, which equation could you use to find the value of a?


A.(7+4)²=a²

B.7²-4²=a²

C.4⁴+a²=7²

D.7²+4²=a²


WILL MARK BRAINLEST FOR CORRECT ANSWER.​

Answer 1

The answer is D because they are both legs and you are looking for the hypotenuse

Answer 2

Answer:

$d \: {7}^{2} + {4}^{2} = {a}^{2}$

Step-by-step explanation:

To find the the hypotenuse of a right triangle, you use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

In the formula above though, c represents the hypotenuse instead of a.
