Question

Can someone help me my grade are bad

Answer 1

Answer:

8.31

Step-by-step explanation:

Using the Pythagorean Theorem:

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

$10^2+b^2=13^2$

$100+b^2=169$

$b^2=69$

$b = \sqrt{69}$

$b = 8.306623863$

The side length for $x$, rounded to the nearest hundredths, would be 8.31.

Answer 2

Answer:

x=√13^2-10^2

x=√169-100

x=√69

x=8.306
