Answer 1

@Johnbc

Answer 2

or this one https://wcps6429-millbrookhs-ccl.gradpoint.com/Resource/3750901,7B0,111,0,0,0,0/Assets/testitemimages/geometry_b/circles/mc069-1.jpg
What is the value of d to the nearest tenth?

14.3
29.3
26.5
33.8

Answer 3

With squares inside a circle, the opposite angles will add up to 180 degrees so if the opposite of angle d is 100 degrees what would angle d be?

Answer 4

50 ?

Answer 5

If we add the 100 degrees + 50 degrees we see that it only equals to 150 degrees not the 180 degrees since they are opposite of each other so ww know that can not be it.

Answer 6

\[180 = 100 + x\]

Answer 7

so its 80

Answer 8

Yup Good Job!

Answer 9

thank youu can you help me out on that other one i put up

Answer 10

Yes, there is a theorem to your problem but i am not very good at explaining it so i will show you a walkthrough without numbers and hope you can solve it the same way

Answer 11

If we want to find D then we will have to go through the process of two secants intersecting each other. \[(A+B) \times A = (C+D) \times C\]

Answer 12

how do you find d ?

Answer 13

If we substitute what we know for all our line segments then we have:\[(22+40) \times 22 = (26 +D) \times 26\]

Answer 14

14.3 ?

Answer 15

No lets do it out

Answer 16

14.3
29.3
26.5
33.8
those are the choices i plugged allof them in and the others didnt go

Answer 17

make sense *

Answer 18

i did that

Answer 19

Well we have not evaluated the right side yet so maybe we can catch your mistake

Answer 20

idk how to find d

Answer 21

We can perform the same thing to both sides to remove the 676 and 26 from the D to solve for D

Answer 22

im confused

Answer 23

what would i do next

Answer 24

round to the nearest tenth it would be 26.5

Answer 25

Correct

Answer 26

Great Job! you are a fast learner

Answer 27

than k you . i have two problems i solved but idk if they are right

Answer 28

Alright lets review them?

Answer 29

i want to show you if they are correct

Answer 30

ok

mc008-2.jpg is tangent to circle A at B and to circle D at C. What is AD to the nearest tenth?

20.2
19.2
25.5
21.5
i got 21.5

Answer 34

The first problem im not understand if the angle is with or without the angle between the arrow and the 2nd problem not sure what the question is i think you pasted the link to the picture instead of the question?

Answer 35

its showing good when i click the link

Answer 36

the first one looking for b

Answer 37

oh the 2nd one is saying what is measure angle BC
