Can someone me? i don't understand question d.

Step-by-step explanation:

From the previous answers you know the angles and side lengths of the triangle:

α = 60°

Ф = 30°

and the side lengths:

1,2 and √3.

Remember:

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

Now you can read off from the triangle:

sin 30° = 1/2

cos 60° = 1/2

sin 60° = √3/2

cos 30° = √3/2

tan 30° = 1/√3

tan 60° = √3

answer: c.
