Question

Please help. (picture)

Answer 1

do you know any angle measurements?

Answer 2

sorry. i would help yo if i could. :/

Answer 3

You have to solve the triangle on the bottom?

Answer 4

What does the Question statement say?

Answer 5

Can you upload the picture of the whole Paper this Question is on?

Answer 6

Usually I'm Pretty Good with Triangles, don't know why I can't figure this out...

You might want to ask someone else. :/

Answer 7

That's pretty complex trigoniometrics

Answer 8

I wish we could just call them similar triangles!

Answer 9

it's obvious from the picture they aren't

Answer 10

You can only use pythagorea's with a right triangle

Answer 11

you do know basic trig right?

Answer 12

i guess i can solve the last question by using the cosine formula\[\large a^2=b^2+c^2-2bc*\cos(\alpha)\]

Answer 13

dude this one is tought i would set up a system of equations showing all that you know
Hold up

Answer 14

wow trigonomitry

Answer 15

do u still need help

Answer 16

like i said fill a linear equation with all you know at first with law of sines :)

Answer 17

@timo86m he's rightt

Answer 18

second one i get approx. 36 but it's a whole lot of equations.

Answer 19

and that is assuming the two angles at b are equal

Answer 20

That could work try it out the angle BIsector theorem

Answer 21

you will plug in the blue part into wolfram.

HOWEVER i am using maple so the lback is what i typed in.

Answer 22

I explained it that computers are to dumb to understand

a=b=c
e=f=d
h=i=j

so you have to tell it to do it like so (notice to use commas. Also they pivot around the middle letter. It is used twice so copy paste)
a=b,
b=c,

e=f,
f=d,

h=i,
i=j,


Here it is with your numbers replaced by the trig ratios

Answer 23

OOPS i meant this attachment not the one above

Answer 24

6/sin(b) = DB/sin(C), DB/sin(C) = 24/sin(D), 15/sin(B) = 24/sin(A), 24/sin(A) = x/sin(C), BD/sin(A) = 9/sin(b), 9/sin(b) = x/sin(D)

here it is ready to by copy and pasted for wolfram :)

Answer 25

WOlfram is refusing to take it :( sorry it has before

In maple it did it for me and i got an answer :)

Answer 26

WOlfram has done it before :(


Look for any system of linear equation solver. This is not a linear equation technically but it can still be used to solve it.

Answer 27

Turns out wolfram still does it but not when it comes to trig :(

Answer 28

here is what maple gives for first one


A = arcsin((1/9)*BD*sin(b)),
B = arcsin((5/72)*BD*sin(b)),
BD = BD,
C = arcsin((1/6)*BD*sin(b)),
D = arcsin(4*sin(b)),
DB = BD,
b = b,
x = 36

answer is 36 but noticed how it solved for A B C D angles maybe that is the key

Answer 29

It solved for those angles i mentioned and put it interms of b :) the small angle.
