Answer:

1. $\frac{\sqrt{13} }{3}$

2. 3.2362

3. $\frac{60}{11}$

Step-by-step explanation:

1.

Cot is the trigonometric ratio defined by "adjacent" over "opposite". <em>So, adjacent = 2 and opposite = 3.</em>

By pythagorean theorem, we have the "hypotenuse" as $\sqrt{2^2+3^2}=\sqrt{13}$

Csc is defined as the trig ratio "hypotenuse" over "opposite". <em>We know the sides, so Csc $\theta$ = $\frac{\sqrt{13} }{3}$ </em>

<em />

<em>First answer choice is right.</em>

<em />

2.

By definition, Csc $\theta$ is the inverse of Sine $\theta$ . <em>If given the value of sin theta, to find value of csc theta, we take the reciprocal of it. Hence:</em>

$Csc\theta=\frac{1}{0.3090}\\=3.2362$

Third answer choice is right.

3.

By definition tan and cot are inverse of each other. <em>So the value of tan is the reciprocal of the value of cot.</em> We can simply "flip" the value of tan theta to get the value of cot theta. Hence:

$Cot\theta=\frac{60}{11}$

Third answer is right.

Answer:

yes

Step-by-step explanation:

if you do 6^3 you get 216

6*6*6=216

6*6=36

36*6=216

2*2*2*3*3*3=216

2*2=4

4*2=8

8*3=24

24*3=72

Anon25 [30]

Answer:

She can cut 24 ribbon from this long strip.

Step-by-step explanation:

Given that,

Bella needs identical strips of ribbon measuring 3.5 feet each.

She has 85 feet of ribbon.

3.5 feet is length of 1 ribbon.

1 feet is length of $\frac{1}{3.5}$ ribbon

85 feet is length of $\frac{1\times 85}{3.5}$ ribbon

≈24.28

$\frac{85}{3.5}=\frac{85\times10}{35}=\frac{85\times2}{7}=\frac{170}{7}$
