Question

If sec4A = cosec (A - 20") and A < 90", then A is equal to
(1) 88
(2) 22
(4) 35​

Answer 1

Answer:

answer is 22 second no.

this is the answer

Step-by-step explanation:

as we know sec is reverse of cosec so 4a+a-20=90

Answer 2

Answer:

option 2 is the answer

Step-by-step explanation:

• The sum of two angles is 90° then they are called complementary angles.
• Complementary angle of A is (90-A)
• SecA=Cosec(90-A)
• SinA =Cos(90-A)
• Cos A=Sin(90-A)
• CosecA=Sec(90-A)
• TanA=Cot(90-A)
• CotA=Tan90-A)
