<h3>Answer</h3>

c. a = 3√2, b = 6√2

<h3 /><h3>Explanation</h3>

#1.First, you find the opposite of the left triangle using sin formula

#2.After you get the opposite, find the b using sin formula and a using tan formula

<h3>Known</h3>

•Right triangle

Hypotenuse = 6

Adjacent = ?

Opposite = ?

• Left triangle

Hypotenuse = b

Adjacent = a

Opposite = ?

<h3>Question</h3>

a. adjacent of right triangle

b. hypothenuse of left triangle

<h3>Way to do</h3>

#1. Sin(∅)= opposite/hypotenuse

sin(45) = opposite/6

opposite = sin(45) × 6

opposite = 3√2

#2. a. tan(∅) = opposite/adjacent

tan(30) = 3√2 / a

a = 3√2 : tan(30)

a = 3√6

b. sin(∅) = opposite/hypotenuse

sin(30) = 3√2 / b

b = 3√2 : sin(30)

b = 6√2

#and so the a = 3√2 and b = 6√2

#you are welcome

In order to set rates, an insurance company is trying to estimate the number of sick days that full-time workers at an auto repa
kotegsom [21]

Answer: 31

Step-by-step explanation:

Formula to find the sample size is given by :_

n=(\dfrac{z^*\cdot \sigma}{E})^2

, where z*= critical value corresponds to confidence level.

\sigma = population standard deviation.

E= Margin of error.

As per given , we have

\sigma=2.8

E=1

We know that critical value corresponding to 95% confidence level = z*=1.96

Then, the required sample size would be :

n=(\dfrac{(1.96)\cdot (2.8)}{1})^2

n=(5.488)^2

n=30.118144\approx31

Hence, the required minimum sample size = 31

How to solve for s with literal equations
olya-2409 [2.1K]
B = (1/6).π.x².s

1st Multiply both sides with 6 → 6B = (6).(1/6).π.x².s. Simplify by 6
6B = π.x².s. Now divide both sides by .π.x².
6B/(.π.x²)  =  .(π.x².s)/(.π.x²) After simplification you get:

6B/(.π.x²) = s →  s = 6B/(.π.x²)
