Answer to Problem 36E

  ∠A=44.4∘,∠B=45.6∘,b=21.4

Explanation of Solution

Given information: Triangle:

Advanced Mathematical Concepts: Precalculus with Applications, Student Edition, Chapter 5.5, Problem 36E , additional homework tip 1

Calculation:

Advanced Mathematical Concepts: Precalculus with Applications, Student Edition, Chapter 5.5, Problem 36E , additional homework tip 2

This is the sketch of the triangle. We are told a = 21 and c = 30 and asked to solve for missing parts.

Since we have two sides, we start with an angle. From angle A we know the opposite and hypotenuse so we do sin−1

  sin−12130=∠A∠A=44.4∘ so ∠B=90∘−44.4∘=45.6∘b=302−212=21.4

Thus,

  ∠A=44.4∘,∠B=45.6∘,b=21.4
