Answer 1

Answer:

Ans 1. a) True

B) True

C) False

D) False

Ans 2. AB =5 cm

ACB =30

1)Finding BC:

tan 30 =AB/BC

$\frac{1}{ \sqrt{3} } = \frac{5}{bc}$

$bc \: = 5 \sqrt{3} \: cm$

2)Finding AC:

Sin 30 =AB /AC

$\frac{1}{2} = \frac{5}{ac}$

$ac \: = 10 \: cm$

$hence \: bc \: = 5 \sqrt{3} \: cm$

$ac \: = \: 10 \: cm$
