In the right triangle shown, mZA = 30° and BC = 6/2.
How long is AC?

x = 18

Step-by-step explanation:

Since 30-60-90 triangles have a side ratio of y : y√3 : 2y.

Since 2y, here, is 12√3, then y is 6√3.

This means that the side x, is 6√3 * √3, which is:

x = 6√3 * √3

= 6 * 3

x = 18

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
