Question

Beginning of the school year. Trigonometry

Answer 1

Step-by-step explanation:

With 30°-60°-90° and 45°-45°-90° triangles, the sides have common ratios. The ratios for 30°-60°-90° triangle sides are:

• x for the smaller side
• x√(3) for the larger side
• 2x for the hypotenuse

So 4. for example has a shorter side length of 5 units, which means the longer side is 5√(3) units long, and the hypotenuse is 10 units long.

*For 45°-45°-90° triangles, the ratios are:

• x for both sides; which have equal lengths
• x√(2) for the hypotenuse
