Question

PLEASE HELP ASAP THIS IS THE LAST QUESTION and I've been avoiding it and I have to submit this,
find the length of the missing side for this right triangle with sides of 5 and 3.

Answer 1

Answer:

4

Step-by-step explanation:

pythagorean theorem says that A^2 + b^2 = c^2 when A and B are the two sides and C is the hypotenuse of the right triangle.

3^2 + b^2 = 5^2

9 + b^2  = 25

b^2 = 25-9

b^2 = 16

b = 4

The answer is 4

(Just FYI this 3-4-5 triangle is super common.)
