Question

HELP
PLSFind all the missing elements:

Answer 1

B=58 a=6.7 c=1.6

Explanation:

It was right on Acellus

Sorry I cant give a better explanation but this unit is killing me.

Answer 2

a = 6.7 , c = 2.0

Explanation:

For side a

To find the missing side a we use the sine rule

`( |b| )/( \sin(B) ) = ( |a| )/( \sin(A) )`

From the question

B = 58°

b = 6

A = 109°

Substituting the values into the above formula we have

`(6)/( \sin(58) ) = ( |a| )/( \sin(109) )`

`|a| \sin(58) = 6\sin(109)`

Divide both sides by sin 58°

`|a| = (6 \sin(108) )/( \sin(58) )`

a = 6.728791

a = 6.7 to the nearest tenth

For side c

To find side c we use the sine rule

That's

`( |b| )/( \sin(B) ) = ( |c| )/( \sin(C) )`

C = 13°

`(6)/( \sin(58) ) = ( |c| )/( \sin(13) )`

`|c| \sin(58) = 6 \sin(13)`

Divide both sides by sin 58°

`|c| = (6 \sin(13) )/( \sin(58) )`

c = 1.591544

c = 2.0 to the nearest tenth

Hope this helps you
