Question

What are the missing angles

Answer 1

Missing sides or angles??

If it's missing sides... Then using sine rule

A/ sin A = B/ sin B

Let sin A =30° and A=8

Let sin B=60° and B =?

Hence 8/sin 30°=B/sin 60°

Multiplying 8 x sin 60 =B sin 60

6.928 = 0. 5B

Dividing both sides by 0.5

Hence B= 13.856

doing same for side c

Let sin A =30° and A =8

Let sin c =90° and C =?

Hence 8/sin30° = C/sin 90

Sin 90° x8 =. 0.5c

Sin 90=1

1x8 =0.5c

Dividing both sides by 0.5 gives 16

Hence C=16
