Find BC

(round to the nearest hundredth)

Given:

In ΔABC, ∠C = 90°, ∠A = 50° and AB = 3 unit.

To find the value of BC.

Formula:

By Trigonometric Ratio we get,

Now,

With respect to θ = 50°, AB is the hypotenuse and AB is the opposite side.

So,

      (approx)

Hence,

The value of BC is 2.3 units.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
