Answer:
Option (d) is correct.
[tex]\tan A=0.5714[/tex]
Step-by-step explanation:
Given : A right angled triangle with given dimensions.
We have to find the value of [tex]\tan A[/tex]
Consider the given right angled triangle.
Using trigonometric ratio,
The tangent of angle is the ratio of perpendicular to the base.
Mathematically written as [tex]\tan\theta=\frac{Perpendicular}{base}[/tex]
For the given triangle
[tex]\theta=A[/tex] , base = 21 and perpendicular = 12
Substitute, we have,
[tex]\tan A=\frac{12}{21}[/tex]
Simplify, we have,
[tex]\tan A=0.5714[/tex]
Option (d) is correct.
