Find the length of the unknown side. Round your answer to the nearest tenth.
Paraphin [41]

Answer:

<em>The correct option is:  11.5</em>

Step-by-step explanation:

Suppose, the length of the unknown side is  x

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and x.

As the given triangle is right angle triangle, so <u>using Pythagorean theorem</u>, we will get.........

8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5

<em>(Rounded to the nearest tenth)</em>

So, the length of the unknown side is 11.5

Need to also show work but confused
Levart [38]

Answer:

S = 2

Step-by-step explanation:

1st step: Simplify both sides of the equation

4/5 s - 3/4 s = 1/10

4/5 s + -3/4 s = 1/10

(4/5 s + -3/4 s) = 1/10 (combine like terms)

1/20 s = 1/10

1/20 s = 1/10

step 2: multiply both sides by 20

20 * (1/20 s) = 20 * (1/10)

s = 2

Hope this helped!
