Hi,

$\sqrt{163} = 12.76$

There are no other simple steps to reduce the square root of one hundred and sixty-three.

The actual square root value is ≈12.767145334803704

But we have taken only significant figures and it is as 12.76.

Hope it helps! :)

Can someone please help me? I don't understand question d.

Answer:

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
