Algebra 1B Unit 4 lesson 8 Help!!!!!!

1. What is the side length b in the triangle below?
A. 625
B. 25
C. 22.96
D. 527

Answer 1

Since you have a right triangle, you can use the Pythagorean Theorem.

\(a^2 + b^2 = c^2\)

Answer 2

ok I have no idea how to do that @mathstudent55

Answer 3

In your problem, a is 5, and c is 13.
You need b.

Answer 4

Now you substitute the values you have for a and c in the equation of the Pythagorean theorem, and you solve for b.

Answer 5

\(a^2 + b^2 = c^2\)

\(5^2 + b^2 = 13^2\)

What is \(5^2\) ?
What is \(13^2\) ?
