### 2 Points, 2 Angles, where does it land?

Hi again, I have a new problem I was hoping to gets some help with...

a triangle has 3 points

Point A is located at 2, 17.5
Point B is located at 1,1
Point C is unknown

Angle A is 82.85
Angle B is 60.89
Angle C is 36.26

Can someone help me with how I would get the plotted points for C please?

I know C's points are 26,13 but I wanted to know how I actually get the two points, thank you!

### Re: 2 Points, 2 Angles, where does it land?

ahh, I think I figured it out...

I can use the same formula from my last post to get the distance between angle A and C

Once I have that, I can use the angle of A to C then do this...

x = 27.73 × cos( 25.64 °) = 25 + 1 =26
y = 27.73 × sin( 25.64 °) = 12 + 1 =13
