Question

What is the value of tan R? Round to four decimal places if needed.

Answer 1

Tan R = 20/21
tan R = 0.9524

answer is C. 0.9524

Answer 2

As per the trigonometry rules , in a right angled triangle tan R is given as:

$tan R = \frac{Perpendicular}{Base}$

Now from the given figure we have

Perpendicular = 20

Base =21

Plugging these values in the formula given above:

$tan R = \frac{20}{21}$

tan R = 0.95238

Rounding it off , we get

tan R = 0.9524

Answer: option third , 0.9524
