Question

Help ppppppppppppllllllllllllllllsssssssss

Answer 1

Choice A is correct.

Explanation:

We have given the the value of tan Ф = -3/8

We have to find the value of cot Ф.

As we know that cot Ф is the reciprocal of tan Ф.

So, cot Ф= 1/tan Ф

cot Ф = 1/(-3/8)

So, choice A is correct.

Answer 2

The answer is 1/(-3/8) ⇒ the first answer

Explanation:

∵ cotФ = 1/tanФ

∵ tanФ = -3/8

∴ cotФ = 1/(-3/8)
