Question

What is the measure of PQ?

Answer 1

In circle T, ∠PTQ ≅ ∠RTS.

Answer 2

cant upload picture

Answer 3

is it like this?

Answer 4

You can press the pencil-button on the top-right of my drawing to draw on it.

Answer 5

Oh okay.

So you see how there are 2 triangles in there?

Answer 6

yea

Answer 7

The 2 triangles are the same (or congruent).

Because the angles from the middle are the same.
And since it's a circle, all the sides of the triangle are the same. (The radius doesn't change).

Answer 8

What is the measure of ?

24°
33°
48°
66°

Answer 9

What is the measure of what? your question didn't say what angle.

Answer 10

pq

Answer 11

Oh that's the same as SR. Remember how the 2 triangles are the same?
It's also 66 then.

Answer 12

Which kind of triangle must triangle XYZ be?

an equilateral triangle
an isosceles triangle
a scalene triangle
a right triangle

Answer 13

Hmm..
It looks like XY and YZ have the same lengths so it'll be an isosceles.

Answer 14

A point is on a circle if the distance from the center of the circle to the point is equal to the

area.
circumference.
radius.
diameter.

Answer 15

Do you know what that red line is called?

Answer 16

radius

Answer 17

Yeah. That's what the question was describing.

Answer 18

What is the length of the radius, r?

8 units
10 units
12 units
16 units

Answer 19

?

Answer 20

Sorry uh...I'm still thinking about it

Answer 21

take your time

Answer 22

I'm going to make one assumption.

"KL is tangent to circle J." Otherwise I don't think it's possible to solve this.

Answer 23

yea it is tangent to J

Answer 24

let me look at this a little more

Answer 25

GOT IT.

So you know what the Pythagorean theorem is right?

Answer 26

know of it

Answer 27

\[(Leg)^2 + (Leg)^2 = (Hypotenuse)^2\]

If we use it here:
\[(r)^2 + (24)^2 = (r+16)^2\]

Answer 28

So if we simplify that it becomes
\[r^2 + 24^2 = r^2 + (2)(16)(r) + 16^2\]
and that becomes
\[24^2 =32r + 16^2\]

Answer 29

Are you able to solve for 'r' from here? or would you like me to help.

Answer 30

yea

Answer 31

its 10

Answer 32

Welp. There's your answer.

Answer 33

In the diagram of circle C, m∠VWX is 43°. What is m?

39°
41°
78°
82°

Answer 34

would i do the same for this

Answer 35

No since none of them are tangents. Tangents make a right-angle. And you can only use pythagorean theorem for right-angle triangles.

Answer 36

Okay wait, where is 'm' at?

Answer 37

there is no m

Answer 38

So uh what are we looking for?

This is what you asked

Answer 40

What is mvx?

Answer 41

oh

Answer 42

Sorry I messed up xd, anyways there's the formula.

Answer 43

Can you solve for VX in this equation:
\[43 = \frac{125-VX}{2}\]

Answer 44

82?

Answer 45

I got 39.

43 x 2 = 125 - VX
86 = 125 - VX
VX = 125 - 86
VX = 39

Answer 46

ok i get it

Answer 47

In circle O, what is m∠MAJ?

Answer 48

I actually don't know how to solve this without assuming A is right underneath O. xd. Are there answer choies?

Answer 49

no answer choices

Answer 50

Yeah shoot. i can't help anymore sorry.

Answer 51

@ThisGirlPretty Are you able to help with this question?

Answer 52

What is the area of the sector that is not shaded?

12
24
120
144

Answer 53

My brain is burned out.

You know the area of a circle right?
In here it would be 12^2 * pi
Which is 144pi.

Then you know that a circle is 360 degrees right? And you're only trying to find (360-60) degrees of it. That's 300/360 or 5/6 of the circle.

So you divide 144pi by 6 and multiply it by 5.
5*144pi/6 = 120pi.

Answer 54

I can't help anymore. I'm gonna suffer some mental trauma.

Answer 55

help tomorrow ?

Answer 56

thank you

Answer 57

If you get on maybe xd.

Answer 58

what is that

Answer 59
