Measure the lengths of the sides of ∆ABC in GeoGebra, and compute the sine and the cosine of ∠A and ∠B. Verify your calculations by finding the sine and cosine of ∠A and ∠B using a calculator

Step-by-step explanation:

Given

I will answer this question using the attached triangle

Solving (a): Sine and Cosine A

In trigonometry:

and

So:

Substitute values for BC and BA

Substitute values for AC and BA
