Question

PLEASE HELP!! One angle of a triangle measures 65º. The side opposite this angle has length 10. If the area of the triangle is 20, find the perimeter.

Answer 1

Drawing triangle would be good start.

Answer 2

i got that far, but I did not know what to do next.

Answer 3

What did you recently learn?

Answer 4

I mean, what math topic are you currently on?

Answer 5

I learned about sine, cosine, and tangent, but for this problem I am not allowed to use the formula \[K=\frac{ 1 }{ 2 }bc sinA\]

Answer 6

If I were able to use this formula, I would get the correct answer, which is perimeter=25. IS there another way to solve this problem without using that formula?

Answer 7

Can you explain how you got 25?

Answer 8

To me, it seems like there is not enough given information. What do you think? @satellite73

Answer 10

Answer 11

Wow, I tagged some good helpers, yet none of them want to help you...

Answer 12

i wonder why

Answer 13

Me too...

Answer 14

So that is what I did to get the answer, but i cant use the formula.

Answer 15

maybe they are not helping because the problem is too hard.

Answer 16

or maybe they are not online

Answer 17

Hmm. And this problem prohibits you to use law of sines?

Answer 18

The only formula we can not use is what I used in the first line of the problem. Without that formula I do not know how else to solve the problem.

Answer 19

I am now trying to draw a circle around the triangle and use geometry theorems to find the answer. But still having trouble :(

Answer 20

Me too...

Answer 21

To be honest, I suck at Geometry, but I have a feel that this can help you...
