Question

in ∆ABC angleB=90° and angleC =30° then AB:AC is​

Answer 1

Answer:

60° is the answer as triangle is equal to 180°

Answer 2

∆ABC angleB=90° and angleC =30°

so the angles of ∆ABC

angle A = 60

angle B = 90

angle C = 30

so the sides are

AB = opposite 30 (angle C) = x

BC = opposite 60 (angle A) = (root 3) × x

AC = opposite 90 (angle B) = 2x

AB:AC = x:2x = 1:2

hope it helps...
