Question

evaluate:sin A+cosA/secA+cosecA;if tan A =12/5​

Answer 1

Answer:

60

Step-by-step explanation:

Your question :sin A+cosA/secA+cosecA;if tan A =12/5

tanA=12/5

or, sinA/cosA=12/5

i. e sinA=12

and cosA=5

so, secA= 1/cosA= 1/5

cosecA= 1/sinA= 1/12

Answer :

sin A+cosA/secA+cosecA

=12+5 /(1/5+1/12)

=17/ (17/60)

=17*60/17

=60
