Question

If cot A= 7/8, evaluate 2 tanA cotA. [1]

Answer 1

Answer:

2

Step-by-step explanation:

2×tanA×cotA

=2×tanA×1/tanA

=2×1

=2

Answer 2

Answer:

2

Step-by-step explanation:

Cot A = 7/8

2 tan A =2( 1/cot A)

:. 2(1/ 7/8) × 7/8

2(1×8/ 7) × 7/8

2(8/7)× 7/8

2(1)

= 2

Therefore your answer is 2.
