Question

Find the value of in the triangle shown below.
Choose 1 answer:

Answer 1

Answer:b

Explanation:

the answer is d because 13^2-12^2=b^2

Answer 2

B: 5

Explanation:

The pythagorean theorem says a^2 + b^2 = c^2, which when reversed, can equal c^2 - a^2 = b^2

Here, 13 is c, 12 is a, and x is b

13^2 = 169

12^2 = 144

169 - 144 = 25

The square root of 25 is 5, leading our answer to be b.
