Use a calculator to find a value of θ between 0° and 90° that satisfies the statement. Write your answer in degrees and minutes

Julli [10]

Answer:

$\theta = 14.1\ degrees$

$846\ minutes$

Step-by-step explanation:

Given

$csc(\theta) = 4.1191$

Required

Solve for $\theta$

$csc(\theta) = 4.1191$

$csc(\theta) = \frac{1}{sin(\theta)}$

So, we have:

$\frac{1}{sin(\theta)} = 4.1191$

Invert both sides

$sin(\theta) = \frac{1}{4.1191}$

$sin(\theta) = 0.2428$

Take $sin^{-1}$ of both sides

$sin^{-1} sin(\theta) = sin^{-1}0.2428$

$\theta = sin^{-1}0.2428$

$\theta = 14.0518577574$

$\theta = 14.1\ degrees$ --- approximated

Convert to minutes:

$1\ degree = 60\ minutes$

So:

$14.1\ degrees = 14.1 * 60\ minutes$

$14.1\ degrees = 846\ minutes$

What is the following quotient?

Sergio039 [100]

Answer:

$\frac{\sqrt{3} }{4}$

Step-by-step explanation:

$\frac{1}{1+\sqrt{3} }$

basically we want to get rid of the √3 on the denominator

to do so we multiply it by itself so it is a perfect square

but whatever we do to the top we must do to the bottom so we multiply the numerator and denominator by √3

$\frac{1*\sqrt{3} }{1+\sqrt{3}*\sqrt{3} }=\frac{\sqrt{3} }{1+\sqrt{9} } =\frac{\sqrt{3} }{1+3} =\frac{\sqrt{3} }{4}$

notes : √3 × √3 = √9 which is a perfect square that simplfies to 3
