anonymous · Answer

$$\beta = 180 - 90 - 55 $$
the rest depends on where the degrees are ($$\alpha$$) AB ? is AC or AB 90 degrees?

anonymous · Answer

i dont get you...

anonymous · Answer

$$ \beta $$ is understood ? (triangle has a sum of all degrees 180)

anonymous · Answer

yea

anonymous · Answer

ok , ... the rest, is depending on where the angles alpha is. between A and B or AC or BC.

anonymous · Answer

ah ok ... understand. AB a line not a product. let me think.

anonymous · Answer

so to find AC, I would just look at angle alpha

anonymous · Answer

sry no time anymore, you need to use sin and cosinus.
than you can use pytagoras

anonymous · Answer

sin and cosine how?
