Question

CosecA+2 equal to 0then Ais

Answer 1

To Find,

Cosec A + 2 =0

Cosec A = 0 - 2

Cosec A = -2

1/ Sin A = -2

Sin A = -1/2

Sin A = -Sin 30*

Sin A = Sin ( -30*)

A = -30*

Formula used

Cosec A = 1/SinA

thanku for your Question.

plz mark my answer as brainliest.

Answer 2

Answer:

A=330

Step-by-step explanation:

cosecA+2=0

cosecA=-2

sinA=-1/2

-sinA=1/2 sin(-A)=-sinA

sin(-A)=30^o

A=330^o
