Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

(8sqrt(3))^2 + b^2 = 16^2

64 * 3 + b^2 = 256

192 + b^2 = 256

b^2 = 64

b = 8

The ratio of the lengths of the sides of this triangle is

8 : 8sqrt(3) : 16

which reduces to

1 : sqrt(3) : 2

This is the ratio of the lengths of the sides of a 30-60-90 triangle.

Hello there! :)

Answer: $\frac{1}{343}$

*The answer must have a fraction.*

Step-by-step explanation:

Lesson: Zero and Negative Exponents.

Distributive property: a(b+c)=ab+ac

First, you apply exponent rule.

$a^b*a^c=a^b^+^c$

$7^-^3$

$\frac{1}{7^3}=7^3=7*7*7=343$

Final answer: $\frac{1}{343}$

Hope this helps!

Thanks!
