Answer:

We can use line segments QR and the points on it to find the slope.

The equation for slope is y2 - y1 / x2 - x1 where x1 is the x value of the first point you chose, y2 is the y value of the second point you chose and so on.

By using this eqution we can pick any 2 points on the line. I will pick q which is (1, 3) and R which is (5, 4)

y2 - y1 / x2 - x1

4 - 3 / 5 - 1

1/4 is the slope

Multiply the two brackets together

(6r)(-88)=-528r

(6r)(-3)=18r

(-1)(-88)=88

(-1)(-3)=3

-528r-18r+88+3 ( combine like terms)

Find the missing side round to the nearest tenth can someone please help me this is my last question

jeka57 [31]

The question is related to trigonometric ratio rule .

In the given diagram, there is a right angle triangle, with adjacent =57, and the unknown side is y. Given angle measurement is 39 .

To find the measurement of y, we will use tan rule which is

$tan \Theta = \frac{opposite}{adjacent}$

$tan 39=\frac{y}{57}$

y = 57 tan 39 = 46.2

The figure shows three exterior angles of triangle ABC. Show that the measure of angle 1 plus the measure of angle 2 plus the me

ivolga24 [154]

Step-by-step explanation:

Let the angle near point A be $A$ .

Let the angle near point B be $B$ .

Let the angle near point C be $C$ .

Let the external angle near point A be $extA$ .

Let the external angle near point B be $extB$ .

Let the external angle near point C be $extC$ .

According to exterior angle property,exterior angle of an angle is the sum of other two angles.

So,

$extA=B+C\\extB=A+C\\extC=A+B$

According to angle sum property,the sum of angles in the triangle add to $180$

$extA+extB+extC=B+C+A+C+A+B=2(A+B+C)=2\times 180=360^{0}$

What is the equation of a circle with center (9,-7) and radius 2?

kirza4 [7]

Answer:

B. (x-9)^2 + (y + 7)^2 = 4

Step-by-step explanation:

The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Hopefully you can memorize that, because it's very helpful in these problems!

(h,k) is our center, and r is our radius, so plug those values into the standard form:

(x - 9)^2 + (y + 7)2 = 2^2

2^2 = 4, so

B. (x - 9)^2 + (y + 7)2 = 4 is our answer!
