Consider a right triangle with leg b = 7.1 and opposite angle B = 39.3. Using a calculator, determine the other angle and the remaining sides of the triangle. Express your answers using at least one decimal place.

i. a = 8.7, b = 7.1 and c = 11.2

ii. A = , B = and C =

Step-by-step explanation:

Given a right triangle with, b = 7.1 and B = .

I. Applying the trigonometric function to determine leg a, we have;

Tan θ =

Tan =

a =

  = 8.675

The length of leg a is 8.7.

ii. To determine leg c,

Sin =

              =

⇒c =

     = 11.21

The length of leg c is 11.2.

iii. Given that: B = and C =

Then,

A + B + C =  (sum of angles at a point)

A + + =

A + =

A = -

  =
