Answer:
A) slope = p/q
Step-by-step explanation:
Slope of any given can be found using the formula, .
In this case, using similar triangles, the rise over the run of any of the given similar triangles will give us the slope of line AB.
This means, slope of line AB would be:
.
✅Therefore, slope of line AB = p/q
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.
