Answer 1

Step-by-step explanation:

so final ans is -120/119 hope it helps

Answer 2

Given,

• tan A = -5/12

To find,

• Tan 2A

Solution,

The value of Tan2A, if tanA=-5/12 should be -120/119.

We can simply find the value of Tan 2A by using the following formula,

     Tan 2A = 2 tan A / 1-tan² A

Substituting the value of tan A in the above formula, we get

    Tan 2A = 2 (-5/12) / 1-(25/144)

                 =   -5/6 / 119/144

                 =  -5/6 * 144/119

                 = -120/119

∴ The value of Tan 2A is -120/119.

Hence, the value of Tan2A, if tanA=-5/12 should be -120/119.
