Question

Find the length of side b in the right triangle below. Round to the nearest tenth if necessary A. 8

B. 16
C. 32
D. 64​

Answer 1

8

Explanation:

Use pythagorean therom: a^2 + b^2 = c ^2

6^2 + b^2 = 10^2

36 + b^2 = 100

b^2 = 64

square root both sides to get rid of the ^2

sqaure root of 64 = 8

square root of b^2 = b

b = 8

Answer 2

A

Explanation:

Use the Pythagorean Theorem( a^2 + b^2 = c^2(hypotenuse)

6^2 + b^2 = 10^2

36+b^2 = 100

b^2 = 64

b = 8(Use square root rule)

A

Hope this helps! Have a nice day!
