Given Trinagle ABC with A(-4, -2), B(4,4), and C(18,-8), answer the following questions.

1 answer:

8 0

For the answer to the question above, the slope of segment AC is (-6/22) = -3/11.

The slopes of perpendicular lines are negative reciprocals, so
you know that the slope of the perpendicular bisector will be 11/3.

The midpoint of segment AC is (7, -5).

Now you have the slope of the perpendicular bisector, and a
point on it. You should be able to complete the equation now.

Notice how sneaky this question is. You don't need to know
point-B at all, and you don't even need to know that there's
any triangle. All you need to know is points A and C.

-3/4x+5/6y=15<br>x-intercept=<br>y-intercept=

Trava [24]

To make this easier, you need to change the fractions by multiplication.

-3/4x=15 - First, you multiply 4 to both sides of the equation

(4)-3/4x=15(4)

-12/4x=60 - Simplify

-3x=60 - Divide by -3 on both sides

x=-20 -> (-20,0)

Do the same to find the y-intercept, to get (0,18)

A tree casts a shadow 31 feet long when the angle of

Blababa [14]

Answer:

x=24.2198542

ROUND IF NEEDED

Step-by-step explanation:

We are trying to find the height of the tree or the vertical side

We are given

The angle of elevation or the angle at the ground ,38
The horizontal length, 31.

Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle

we are going to use tangent

$\tan(x) = \frac{opp}{adj}$

plug 38 in for x or theta, x for opp side and 31 for adjacent side

$\tan(38) = \frac{x}{31}$

Multiply 31 by both sides to find x

x=24.2198542

ROUND IF NEEDED.
