Find a

Answer 1

Haha, it is right there after the space!

Answer 2

haha XD

Answer 3

i got 12/2 but im not sure if its right

Answer 4

explain your steps please

Answer 5

i know its an improper fraction

Answer 6

how did you get 12/2

Answer 7

just a guess ;lol

Answer 8

i sent you a screen shot of the question

Answer 9

do you know about 30-60-90 triangles. what is the length of "x" ?

Answer 10

phi is here, he will most def walk you through this, just use trigonometric functions , best of luck :)

Answer 11

x 15/2

Answer 12

yes. now notice x is the hypotenuse of the "small" triangle on the left
notice a is opposite the 30 degree angle. what is a ?

Answer 13

a tan60°= b tan30°
do u get this equation?

Answer 14

in other words, you have another 30-60-90 triangle with hypotenuse 15/2 (or 7.5)

Answer 15

@Pawanyadav so that would be A*1.7321 equals b*.5774

Answer 16

2 parts to work with: (1) remember from 'our' last problem, you can make a relationship between similar sides. (2) in a 30-60-90 triangle, one of the sides is half the hypotenuse. Do those help?

Answer 17

Don't convert them in decimal

Answer 18

\[\cos60=\frac{ a }{ \frac{ 15 }{ 2} }\]

Answer 19

would that be a correct way of solving it??

Answer 20

Just keep them in under root
As. a(√3)= b/(√3)
means 3 a= b

Answer 21

Now. use information given in question..
a+b=15
a+3a=15
4a=15
a=15/4

Answer 22

There are lots of ways for this one. I used the results of that other problem: a/x = x/(a+b), and x=(a+b)/2. I remember you saying you are working a section involving similar triangles, so I am trying to keep it in that context..

Answer 23

can you help me find z??

Answer 24

Z ?????

Answer 25

in the diagram

Answer 26

oh wait nvm i can find that using the pythagorean theorem

Answer 27

Yes first u have to find y.

Answer 28

how do i do that?

Answer 29

tan60° =?

Answer 30

wouldn't i use pythagoream theorem??

Answer 31

bc i already know x and a

Answer 32

What are u getting?

Answer 33

well i know \[x^2=a^2 + y^2\]

Answer 34

Do u know x.

Answer 35

7.5

Answer 36

If u know x , u can direct use
x2 + z2=225

Answer 37

z2 is 168.75

Answer 38

you guys still working on this? wow

Answer 39

im not sure but the answer has to fit in the format below

Answer 40

so it cant be in decimal form

Answer 41

So it should be (15√3)/2

Answer 42

well thats the answer i got for y... so whats y?

Answer 43

Use a2+y2=x2

Answer 44

Or y=a tan60°

Answer 45

i got 13

Answer 46

well 12.99

Answer 47

It should be (15√3)/4
