Suppose that ? Is an angle with csc(?)=-12/5 and ? Is not in the third quadrant. Compute the exact value of Tan(?). You don’t ha
Damm [24]

Answer:

tan(\theta)=-\frac{5}{\sqrt{119}}

Step-by-step explanation:

<u><em>The correct question is</em></u>

Suppose that ∅ Is an angle with csc(∅)=-12/5 and ∅ Is not in the third quadrant. Compute the exact value of Tan(∅).

∅ Is not in the third quadrant

If csc(∅) is negative the angle lie in the III Quadrant or in the IV Quadrant

∅ Is not in the third quadrant ----> given problem

so

That means ----> ∅ Is in the fourth quadrant

step 1

Find the value of sin(\theta)

we have

csc(\theta)=-\frac{12}{5}

we know that

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

therefore

sin(\theta)=-\frac{5}{12}

step 2

Find the value of cos(\theta)

we know that

sin^2(\theta)+cos^2(\theta)=1

we have

sin(\theta)=-\frac{5}{12}

substitute

(-\frac{5}{12})^2+cos^2(\theta)=1

\frac{25}{144}+cos^2(\theta)=1

cos^2(\theta)=1-\frac{25}{144}

cos^2(\theta)=\frac{119}{144}

cos(\theta)=\frac{\sqrt{119}}{12} ---> is positive (IV Quadrant)

step 3

Find the value of tan(\theta)

we know that

tan(\theta)=\frac{sin(\theta)}{cos(\theta)}

substitute the values

tan(\theta)=-\frac{5}{12} : \frac{\sqrt{119}}{12}=-\frac{5}{\sqrt{119}}

What is the value of the expression? 16 – 4 + (160 ÷ 20)4
Anarel [89]
16 - 4 + (160 / 20) 4 = 16 - 4 + 8*4
                                 = 16 - 4 + 32
                                 = 46
