Answer 1

Here it is.

Answer 2

@RICARDOismyfirstname

Answer 3

143.24 degrees

Answer 4

the radius of the circle is 6 ; using 2PiR you get 12 Pi ; 15 feet over 12 Pi = .397 ; you multiply that by 360 degrees to get the answer. cheers

Answer 5

Yeah, he got it spot on, But I'm not all too god at that stuff yet.

Answer 6

theta / 360 = 15 / (2(12)pi)

Answer 7

Use the fact that the ratio between the angle and a full rotation (360) is equal to the ratio between the arc length and the circumference (2 pi r)

Answer 8

wow @fiercesteak thank you so much can you help me with one last one? that will be all

Answer 9

@wio could you help me with one last question?

Answer 10

What is it?

Answer 11

here it is

Answer 12

The first question: 20 because in a 30 60 90 triangle, the shortest leg is half the length of the hypotenuse

Answer 13

the second question: if the shortest leg is x the second shortest leg in 30 60 90 triangle is xsqrt3 so it's 10 divided by sqrt 3

Answer 14

All the the triangles are proportional

Answer 15

sorry the first question is wrong; it's the hypotenuse of the 2nd biggest triangle; it's 40sqrt3 over 3

Answer 16

now the answer to the last question is 20

Answer 17

so the second answer would be?

Answer 18

@fiercesteak

Answer 19

second answer would be 10sqrt3 over 3

Answer 20

sorry double that

Answer 21

double the answer?

Answer 22

20sqrt3 over 3

Answer 23

so 11.54?

Answer 24

that's what I got ~~

Answer 25

cool and for the third question the answer would be 20?

Answer 26

yup :)
