Given the following triangle, if b = 9 and b = 15°, find a. 0.27 2.41 33.59

33.59 ( approx )

Step-by-step explanation:

Since, the sum of all interior angle of a triangle is supplementary,

Thus, for the triangle ABC,

∠A + ∠B + ∠C = 180°

Given, ∠B = 15° and ∠C = 90°,

⇒ ∠A + 15° + 90° = 180° ⇒ ∠A + 105° = 180° ⇒ ∠A = 180° - 105° = 75°,

Now, By the law of sine,

In triangle ABC,

We have, b = 9 unit,

Thus, the value of a is 33.59 unit ( approx )
