trigonometry

can someone help me with a trigonometry question

Can you upload the question if you want some advice.

hi the question was the triangle ABC is ab-12cm,bc=10cmand cAb=45 degrees
and I have to find what the values for bAc and aBc are
then find the area

Can you sketch it (and upload)?
What rules do you know that might be useful to find the angles?

I've drawn it but I don't know how to upload it
I still don't know

If you press the camera icon at the top of the Reply, you can upload an image.
For the angles - sides you're given, how are they related?
Is it a right angled triangle?
If not, which (two) rules do you know?
Which one matches the information you're given & want to find.

it not a right angle
the sine and cosine rules

Yes, so which one is appropriate here to find the first angle?

sine 45/10=sinec/12

So solve.
The how do you simply get the third angle?

could you do 180 -45 - 58.05

I’m pretty sure you use the sine rule (don’t forget to label the sides as either a, b and c)

If course.
Then you know two sides and the angle between them, so the area is given by ...

1/2ab sinc

Yes. I've told you nothing here, you know how to do it.

would you be able to help with other
