It would be 30 students from his class roster because not every kid would have his math class in the other options.

Assume that the lines that appear to be tangent are tangent p is the center if each circle find x. ​
Elodia [21]

Answer:

Step-by-step explanation:

Problem One

All quadrilaterals have angles that add up to 360 degrees.

Tangents touch the circle in such a way that the radius and the tangent form a  right angle at the point of contact.

Solution

x + 115 + 90 + 90 = 360

x + 295 = 360

x + 295 - 295 = 360 - 295

x = 65

Problem Two

From the previous problem, you know that where the 6 and 8 meet is a right angle.

Therefore you can use a^2 + b^2 = c^2

a = 6

b =8

c = ?

6^2 + 8^2 = c^2

c^2 = 36 + 64

c^2 = 100

sqrt(c^2) = sqrt(100)

c = 10

x = 10

Problem 3

No guarantees on this one. I'm not sure how the diagram is set up. I take the 4 to be the length from the bottom of the line marked 10 to the intersect point of the tangent with the circle.

That means that the measurement left is 10 - 4 = 6

x and 6 are both tangents from the upper point of the line marked 10.

Therefore x = 6

PLEASE HELP 80 PTS.<br> Math stuff...
White raven [17]

Answer:

a) m∠6 = 55 and m∠8= 55 - 20 --> m∠8= 35     x = 55

b) m∠7 = 40 and m∠9 = 140                                x = 40

c) m∠8 = 46 and m∠7 = 46                                  x = 18

d) m∠6 = 63 and m∠7 = 27                                  x = 9

(just like the note says at the top each one is a different problem hence the different answer or each angle even if its the same one)

Step-by-step explanation:
