Question

In the triangle below, what is the tangent of 30°?

O A.
OB.
-IN
B. √3
OC. 2
O D. 1
60°
2
13
30°

Answer 1

B

Explanation:

tangent formula is the line facing the angle divided by the shorter one. so 1/root3

Answer 2

Option B.

`tan(30)=(1)/(√(3) )`

Explanation:

We can use SOH CAH TOA to find our answer.

In this acronym, O is the opposite side, A is the adjacent side, and H is the hypotenuse.

TOA is for tangent.

So we can say the tangent of angle x is the opposite side divided by the adjacent side.

`tan(x)=(O)/(A)`

In this triangle we are given

`O=1\\A=√(3) \\H=2`

Therefore

`tan(30)=(1)/(√(3) )`
