How to find the hypotenuse of a triangle?

ExtremeBDS [4]

To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem

so $a^{2} + b^{2} = c^{2}$

$a^{2}$ is one of the legs

and

$b^{2}$ is the other leg

then

$c^{2}$ is the hypothenuse

Answer:

5.33

Step-by-step explanation:

move the 4 out of the summation because just a constant multiplier

4 *sum from 1 to 10 for (1/4)^(n-1) [sorry i don't know how to write sums using latex)

The formula for the geometric sum is :

First term*(1-multiplier^n)/(1-multiplier), formally $\frac{a_1(1-r^n)}{1-r}$

Here multiplier is 1/4

First term is (1/4)^(1-1) = 1

Thus the value of sum is $1*(1-(1/4)^1^0)/(1-1/4)$ which equals $(1- (1/4)^1^0)*4/3$

We factored out 4 so its $4*(1-(1/4)^1^0)*4/3$ which is $16/3 * (1- (1/4)^1^0)$

This equals 5.333328247 which is 5.33 to the nearest hundredth
