The terminal side means that it's 16 to the right and 12 up. Which means that the triangle made from this has the sides of 16 and 12 and the hypotenuse is 20 units long. Theta, in this case, would have 16 as it's adjacent and 12 as it's opposite.
Therefore, using the Pythagorean identities:

my answer is in the image above
Answer: b=2(square root of 2) and a=4
Step-by-step explanation:
Since this is a 45-45-90 triangle we know that side b is equal to
.
In a 45-45-90 triangle, the hypotenuse is equal to
this means in order to find missing side length a, we have to multiply
this will give us 4
so the missing side lengths are,
and
