What angle has the same sine value between 0-180? as Sin 24

Inessa05 [86]

Answer:

$Sin156$

Step-by-step explanation:

Given

$Sin24$

Required

Find equivalent between 0 to 180;

Let 24 be represented by $\theta$

So, $\theta = 24$

From Trigonometry ratios;

$Sin\theta = Sin(180 - \theta)$ where $0\leq \theta \leq 180$

Recall that $\theta = 24$

So, we have to substitute 24 for $\theta$ in the above expression.

This gives

$Sin24= Sin(180 - 24)$

Subtract 24 from 180

$Sin24= Sin156$

Hence, the equivalent of $Sin24$ is $Sin156$

3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.

Answer: positive linear association

4) Find the slope using the formula
$m = \frac{y2 - y1}{x2 - x1}$

m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out

Oh no! It seems that their is not a pattern in the association, so its nonlinear!

Answer: Negative nonlinear association

5) $m = \frac{y2 - y1}{x2 - x1}$
m = 80 - 66/ 5 - 3
m = 14/2
m = 7

Positive! But is it linear??
Let us draw a graph this time.

I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!

Answer: Positive nonlinear association

Hope this helped. :)
