• explain the meaning of sine, cosine, and tangent ratios in right triangles

  
  

The calculator shows the sine of 32° is equal to 0.5299.This implies that for pABC:

a = 0.5299 and c = 1.000
a = 5299 and c = 10 000
the length of a is 0.5299 of the length of c
the length of c is 1.887 of the length of a

Explain why each of these statements is true.

Given the following diagram, complete the problems.

Using angle A, identify:
- the side opposite to A
- the side adjacent to A
- the hypotenuse

Write the ratio:
- sin A
- cos A
- tan A
