Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.

A)<br>be<br>85°<br>120°<br>(2x - 10°<br>X​
Lunna [17]

Let's see what to do buddy...

_________________________________

Step (1)

We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :

(n - 2) \times 180

Our figure has 5 sides ;

So , sume the interior angles of it equals :

(5 - 2) \times 180 = 3 \times 180 = 540 \\

_________________________________

Step (2)

First look at the photo which I post.

According it we have :

(180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\

2x - x + 475 - 10 = 540

x + 465 = 540

Subtract the sides of the equation minus 465 :

x = 540 - 465

x = 75

_________________________________

And we're done.

Thanks for watching buddy good luck.

We can use the points (-4, 3) and (3, 1) to solve.

Slope formula: y2-y1/x2-x1

1-3/3-(-4)

-2/7

Therefore, the answer is C

Best of Luck!
