Vicky came home from the matinee at 5: 45 pm the cinema was 1/2 hour each way. she spent 2 1/4 hours at the cinema. what time did she leave home?

you can't solve x because it is 2 linear equation and you only have one equation

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

the answer to this is 4340

hope this if needed hmu
