If tan x° = 3 divided by y and cos x° = y divided by z ,what is the value of sin x°?

DedPeter [7]

Given:
tan x = 3/y
cos x = y/z

Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
= (3/y)*(y/z)
= 3/z

Answer: a) sin x = 3/z

Can someone help me solve this equation? -11v-14=v-14

LenaWriter [7]

Answer:

Step-by-step explanation:

Add 14 on both sides:

-11v+0=v

So we have:

-11v=v

And there is only one number in the universe that can satisfy that and that is 0.

What scale factor was applied to the first rectangle to get the resulting image?

madam [21]

Answer:

The scale factor for the resultant rectangle is $\frac{2}{5}$ units.

Step-by-step explanation:

Given two rectangles with sides 3 units and 7.5 units.

We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.

Scale factor is defined as the ratio of corresponding side of given figure to the corresponding side of resulting figure.

That is $\text{Scale factor}=\frac{\text{length of side of given figure}}{\text{length of side of resulting figure}}$

Here, $\text{Scale factor}=\frac{\text{length of side of given rectangle }}{\text{length of side of resulting rectangle}}$

$\text{Scale factor}=\frac{3}{7.5}=\frac{2}{5}$

Hence, the scale factor for the resultant rectangle is $\frac{2}{5}$ units.
