Question

Find tan 0, where 0 is the angle shown.
Give an exact value, not a decimal approximation.

Answer 1

4/3

Explanation:

Tan(x)=Opposite/adjacent

We need to find the opposite side.

We can use the Pythagorean theorem to help us:

5^2=3^2+x^2

25=9+x^2

16=x^2

x=4

4 is the measure of the opposite side

The adjacent side has measure of 3

Tan(theta)= 4/3

*theta is the weird 0 with a bar thingy at the angle, its some letter in the greek alphabet that denotes an unknown angle in geometry
