Question

tan5a=cota-18. please find the correct answer and say to me as fast as possible

Answer 1

Answer:

a=18

Step-by-step explanation:

tan 5a = cot(a-18)

cot(90-5a)= cot(a-18) [tan 90 -a= cot a]

90-5a=a-18

5a+a=90+18

6a=108

a=18

Answer 2

Answer:

a=18

tan 5a = cot(a-18)

cot(90-5a)= cot(a-18) [tan 90 -a= cot a]

90-5a=a-18

5a+a=90+18

6a=108

a=18

Step-by-step explanation:

tan 5a = cot(a-18)

cot(90-5a)= cot(a-18) [tan 90 -a= cot a]

90-5a=a-18

5a+a=90+18

6a=108

a=18
