How to add vectors with angles.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
