Answer:

The answer is option 1.

Step-by-step explanation:

You have to apply Tangent Rule, tanθ = opposite/adjacent:

[tex] \tan(θ) = \frac{oppo.}{adj.} [/tex]

[tex]let \: oppo. = 5 \\ let \: adj. = b \\ let \: θ = 30[/tex]

[tex] \tan(30) = \frac{5}{b} [/tex]

The correct answer is option (A) tan(30)=5/b

Tangent function

  • The tangent function is one of the main six trigonometric functions and is generally written as tan x.
  • It is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled triangle.

How to solve this problem?

The steps are as follow:

  • The right angle triangle is given whose sides are as follow:

AB = 10 cm

BC = 5 cm

AC = b cm

  • To find the tan(30) we will use following formula:

tan(x) = opposite side / adjacent side

tan(30) = BC / AC

tan(30) = 5 / b

So, the correct answer is option (A) tan(30)=5/b
