Question

Please can someone help me with #7 I am completely clueless and i dont get how my teacher teaches it http://miamibeachhigh.schoolwires.com/cms/lib07/FL01000126/Centricity/Domain/212/chap10-5.jpg

Answer 1

A tangent line means that the line "grazes" the boundary of the circle.

Answer 2

I need way more help

Answer 3

Well, you can answer #1, right?

Answer 4

I guess it is tangent......would i have to do any math for that?

Answer 5

No. Just remember the concept.

Answer 6

For #3, don't you think those two tangent lines are congruent? Create an equation so they are equal to each other. Solve for x.

Answer 7

kk ima do that now

Answer 8

well im really bad at this so i dont think i did it right

Answer 9

You forgot to bring the 'x' on the right over to the left side.

Answer 10

You don't have to take a picture.

Answer 11

well i dont wanna write it over again here and i wanna make sure i get it right

Answer 12

Then do it on your paper and just tell me what you get for x.
You got: 3x = x + 16
You forgot to subtract the x from both sides.

Answer 13

How would you substract x from both sides? would it be 3=16 or 3x=16?

Answer 14

What do you mean? There are two x terms on both sides. 3x - x = 2x

Answer 15

Learn to algebra.

Answer 16

Im horrible at algebra

Answer 17

So 3x turns into 2x and the 16 stays the same

Answer 18

Yes. You have 2x = 16 now.

Answer 19

Ok so 8 is the final answer

Answer 20

Yes lol.

Answer 21

#5 is a straight up pythargorean theorem problem. You're given the hypotenuse and one side.

Answer 22

Lol thanks for not being a jerk and helping and ok

Answer 23

Nah, I can still be a jerk. You should know that when you subtract terms with the same variable, the coefficients do the math, but the variable stays.

Answer 24

Oh trust me i know you can still be a jerk

Answer 25

5x + 6x = 11x
7t - 8t = -t
100n - 23n = 77n

Answer 26

I know I'm a jerk. I don't wanna make you cry.

Answer 27

You did yesterday lol i was gonna tell you to message it to me so you wouldnt get banned

Answer 28

You would've reported me.

Answer 29

Well then now we will never know

Answer 30

Perhaps. Did you do #5 yet?

Answer 31

Im doing it

Answer 32

I was confused and i added QT and PT together and then i did the pythagoream theorem with the hypotenuse already included like you said and i got 13

Answer 33

Whoa what are you talking about. I thought we were on #5.

Answer 34

Lmao sorry i got mad over something and i did the wrong problem

Answer 35

im not blonde

Answer 36

Ok i did #5

Answer 37

You're right. You're worse than blonde. Kappa.
#7, i'm not really sure at first glance.

Answer 38

Hey dont push it

Answer 39

See? That's not even the worse I have. But yeah, I'm not sure how to solve #7 at first sight. I'm tired.

Answer 40

Kay i guess your not gonna help me so i gotta find someone else

Answer 41

You asked about #7.
In #7, there are 6 tangents drawn to a circle from 3 points outside the circle. Each pair of tangents is drawn from one point. That means each pair of tangents is congruent. Since you have the length of one tangent segment of each pair, you can find the length of the other tangent segment of that pair. Then add up all lengths to find the perimeter of the triangle.
