Using Illustration 1, solve each right triangle:

Chapter 13.4, Problem 9E, Using Illustration 1, solve each right triangle: ILLUSTRATION 1 A=68.8,c=39.4m

ILLUSTRATION 1

A = 68.8 ° ,   c = 39.4  m

To determine

To calculate: The lengths of each side and each angle of the illustrated right triangle below where A=68.8° and c=39.4 m,

Elementary Technical Mathematics, Chapter 13.4, Problem 9E

Explanation of Solution

Given Information:

The provided sides are, A=68.8° and c=39.4 m and figure is,

Formula Used:

For a right angled triangle,

The trigonometric ratio for tangent of angle A is

tanA=length of side opposite angle Alength of side adjacent to angle A=ab

sinA=length of side opposite angle Alength of hypotenuse=ac

cosA=length of side adjacent to angle Alength of hypotenuse=bc

According to angle sum property of triangle,

A+B+C=180°

Calculation:

Consider the below figure,

For a right angled triangle,
