Answer:

So we know that these to shapes are scaled copies, so find two angles on them and see what they divid too. Example: A has 2.5 B has 5, if we divide 5 by 2.5 we get 2. And if we times 2.5 by 2 we get 5 as are total. We now know that 2 is going to be the number that helps us crack all of these angles.

<em>B ANSWERS: </em>

Because we know that 2.5 times 2 gets us 5 thats going to be the same answer for the angle on the right. In other words <u>5 is the answer for B's missing right angle.</u>

If we follow the same formula we get <u>3 for B's missing left angle. </u>

<em>A ANSWERS:</em>

This time instead of mutilplying we are dividing. 53/2 gives us 26.5, so <u>26.5 is the answer for the top right angle.</u>

<u></u>

Same dividing, <u>41 is the answer for the bottom left missing angle.</u>

Find the value of r so that the line through (-4,3) and (r,-3) has a slope of 2/3.

Tems11 [23]

Answer:

<h3>r = -13</h3>

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the slope m = 2/3 and the points (-4, 3) and (r, -3). Substitute:

$\dfrac{-3-3}{r-(-4)}=\dfrac{2}{3}$

$\dfrac{-6}{r+4}=\dfrac{2}{3}$ <em>cross multiply</em>

$2(r+4)=(-6)(3)$ <em>divdide both sides by 2</em>

$r+4=(-3)(3)$

$r+4=-9$ <em>subtract 4 from both sides</em>

$\boxed{r=-13}$

Need help and will mark brainlist and thank You

Furkat [3]

Answer:

40

Step-by-step explanation:

Angles ABO, BAO, and AOB are the angles of isosceles triangle AOB. The angles at A and B are equal, so we have ...

AOB +2ABO = 180° . . . . . sum of angles in the triangle

100° +2ABO = 180° . . . . . . use the given value

50° +ABO = 90° . . . . . . . . divide by 2; next, subtract 50°

∠ABO = 40°
