how can i find the length of the hypotenuse in the attached image assuming i know the length of side a + all 3 angles?
also how would i find it if i knew the length of side b + all 3 angles?
heres the calculations i'm using:
'351,151 - centre
'10 + sf.Height - 2nd rectangle top
'30 degrees - 1 o'clock
Dim a As Single = (151 - (10 + sf.Height))
Dim lX2 As Single = 351 + Math.Sin(Math.PI * 30 / 180) * (a / Math.Sin(30))
Dim lY2 As Single = 151 - Math.Cos(Math.PI * 30 / 180) * (a / Math.Sin(30))
to find c ---use - cos30= 107/c
c = 107/cos30
c = 123.6
you can usee - cosx= adjecent side/ hypotenuse
sinx = oposite side/ hypotenuse
then rearrange the eqation to find hypotenuse
you can also find it if you have side b and any 2 angles exept the right angle which is 90deg by using thos formula ===sin30 = b/c
