Cosine is the ratio of the adjacent side to the hypotenuse.

In short, we have this equation
cos(angle) = adjacent/hypotenuse

In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5

The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)

So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5

Answer:

47 million dollars

Step-by-step explanation:

A charity received a donation of 17.9 million. If this represents 38% of the charity's donated funds, what is the total amount of its donated funds. Round your answer to the nearest million dollars.

First, let's set the total funds as x.

If 38% of x is 17.9 million dollars, we can write this equation.

38% * x = 17.9 million.

Simplify.

0.38 * x = 17.9 million

Divide both sides by 0.38.

x = 47.105 million

Round to nearest million

x = 47 million dollars

So, the total amount is 47 million

If one raw contains 3x-2 trees & if the total trees in the rectangle are 24x-16, that means Horizontal Rows x Vertical Rows =Total number of trees:

(3x-2) * Vertical Rows = 24x-16 ===> Vertical Rows =(24x-16) / (3x-2)

Perform the division & you will find Vertical Rows =8

Select all the lines points that are on the line through (0,5) and (2,8)
bazaltina [42]

Answer:

3x-2y-2=0

3x-2y+10=0

Step-by-step explanation:

let the slope of the line be 'm'

and also (x1,y1)=(0,5)

             (x2,y2)=(2,8)

we know the formula for finding slope m=\frac{Y2-Y1}{X2-X1}

m=\frac{8-5}{2-0} \\m=\frac{3}{2}

The equation of the line will be as,

(y-y1)=m(x-x1)\\(y-5)=\frac{3}{2}(x-0)\\ y-10=3x\\ 23x-2y+10=0\\(y-2)=\frac{3}{2}(x-2)\\ 2y-4=3x-6\\3x-2y-2=0
