we need more info. can you make a screen shot of the entire question?

how do i do that

https://www.georgiastandards.org/Georgia-Standards/Frameworks/Pre-Calculus-Unit-3.pdf

that is a link to 43 pages.

you have to scroll all the way down to the bottom

which page?

the very last one

43

ok. It sounds like they want all the angles and sides for each of the triangles

yeah i think so but im not sure how

so i would do a^2+b^2=c^2

yes, and we are looking for c

4^2+3^2=c^2

which equals 25

c^2 = 25
c = sqr(25)

yes, so label side AC with length 5

ok got it

the few pages in front of the last page seem to go through the solution

i saw that to but i dont really understand how they did that

Say the job is to find the sides of all 5 triangles.
so far you know the sides of triangle ABC

ok

we use law of cosine?

\[5^2+3.1623^2-2(5)(3.1623)\cos(71.5651\]

that is c^2
what do you get for c^2 and then c ?

dont you get 35.0-31.623*0.31 and then put that in the calculator?

and i got 25.1 but i have to square root it

I would use the calculator to do the whole computation
\[ 5^2+3.1623^2-2(5)(3.1623)\cos(71.565)\]

you don't want to round any numbers until the very end.

i got 25 still

so what is side AD ?

well when i square root 25 i got 5

so angle a is the same as angle c (71.5652)

If by angle a and angle c you mean < CDA and < ACD

yes

no i dont know anything about the middle angle

\[cosc=a^2+b^2-c^2/2ab\]

so then sin=a/sinA=b/sinB

yes. can you find angle ADE ?

remind me again is the a the side and the A is the degree right

ok \[\sin=\frac{ 7.8102 }{ sinA }=\frac{ 5 }{ \sin38.845 }\]

typo:
\[ \frac{ 7.8102 }{ \sin A }=\frac{ 5 }{ \sin38.8845 }
\]

0.6277524996

i put that in and it says error

you can use google. type into the google search window
sin 38.8845 deg * 7.8102/5=

okay thank you for everything i got the rest your the best
