part 3. Find the value of the trig function indicated, use Pythagorean theorem to find the third side if you need it.

Step-by-step explanation:

Pythagorean Theorem is: a² + b² = c²   , where "c" is the hypotenuse

Note: 4² + (8√2)² = hypotenuse²   →   hypotenuse = 12

Note: 12² + opposite² = 20²   →   opposite = 16

Note: adjacent² + 5² = 6²   →   adjacent = √11

Note: adjacent² + 7² = (13√2)²   →   adjacent = 17
