Help me PLEASE quick I will give you brainliest

Answer 1

Answer:

56. Someone correct me if I'm wrong.

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem, which is a² + b² = c²

a and b are the legs, and c is the hypotenuse. Here, we know the length of one leg and the hypotenuse. So...

a² + 42² = 70²

First, we need to square these numbers. 42² is 1764. 70² is 4900. So...

a² + 1764 = 4900

Now, we can subtract 1764 from both sides.

a² + 1764 - 1764 = 4900 - 1764

That would give us...

a² = 3136

Now, we square root 3136.

So...

$\sqrt{3136}$ = 56

The missing side should be 56.
