I don't know how to do #86-#88. Any help?

SOVA2 [1]

86 and 87 utilize the Pythagorean theorem. Where those tangent lines meet the circle forms a right angle. So you have a side length of 6 and a hypotenuse of 22. So the missing side length is 21.16. For 87, its the same thing, but you have the 2 legs but are missing the hypotenuse.

What do you know about the side lengths and trigonometric ratios in special right triangles

TEA [102]

Explanation:

This looks like an essay question with no right answer.

__

There are two "special" right triangles:

isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2

30°-60°-90° triangle with sides in the ratios 1 : √3 : 2

These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.
