Question

In the figure <A = 30

, <B = 90

, AC = 16cm

a) What is the length of BC?

b) What is the length of AB?​

Answer 1

Answer:

please send the figure

then only we may answer

Answer 2

Answer:

Angle A=90° and B=30°

➡Angle C=90°-30°=60°

➡BC is hyp=8cm long

AC=8/2=4cm(sin 30°=AC/hp) ➡sin 30°AC

AC=8x1/2=4

AB=√(BC^-AC^2=√(8^2-4^2) =√(64-16) =6.93cm

AC=4cm

AB=6.9cm.
