Answer:
Option B
Step-by-step explanation:
Given that cosθ =
Since, θ is an angle in quadrant II therefore, cosine value is negative
Now we will find the tangent ratio from the given triangle.
tanθ =
From the given triangle,
By applying Pythagoras theorem in the given right triangle,
AC² = AB² + BC²
AB² = 10² - 3²
= 100 - 9
= 91
AB = √91
tanθ =
Now, tanθ =
Since, θ is in second quadrant therefore, tangent of the angle will be negative.
tanθ =
Option B is the answer.
