Question

In a right angle triangle ABC with right angle at B, AB = 5 cm and < ACB = 30. Determine the length of AB and AC

Answer 1

Answer:

in triangle ABC,<B=90

AB=5cm,<ACB=30

sin 30= opposite side to <C/hypotenuse

1/2=AB/AC

1/2=5/AC

AC=10cm

cos 30= BC/AC

root 3/2=BC/10

10*root 3/2=BC

BC =5*root 3

Thanks.

Step-by-step explanation:

Answer 2

length of AB is given as 5 in the qn
length of AC can be found out using trignometric values
tan30=5/AC
1/2=5/AC
AC=10
