Answer:

x= 20

Step-by-step explanation:

Hello

I think I can help you with this

a flat angle is, in terms of geometry, the space between an intersection between two lines whose opening measures 180 degrees or 180º. Since the angle is 180º there is no difference between two lines or a line and we can say that the angles in a straight line always add up to 180º.

Step 1

define

according to the graph

3x+80+2x=flat angle=180°

3x+80+2x=180°

Step 2

solve for x

3x+80+2x=180°

5x+80=180

subtract 80 in each side

5x+80-80=180-80

5x=100

divide by 5

(5x)/5=100/5

x=20

Have a great day.

Find an equation for the line perpendicular to y=-1/2x+4 and goes through the point (-1,10)

Artemon [7]

The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.

So, we can make the equation $y=2x+b$ . We need to find b, and put b in.

To find b, put in the numbers of y and x.

$10=2(-1)+b$

Solve for b:

$10=-2+b\\b=10+2\\b=12$

Now replace b in the original equation with 12 and that will be the answer:

The answer is $y=2x+12$ .

Can somebody tell me how to solve these kind of problems?

Ugo [173]

Answer: 918km^2

Step-by-step explanation:

$area(a): 1700km^2\\percentage(p): 5.75 = \frac{5.75}{100}=0.0575\\years(y): 8$

Let x be the new dimension of the area;

$x=a-(a*p*y)$

$x=(1700km^2)-(1700km^2*0.0575*8)\\x=1700km^2-782km^2\\x=918km^2$
