Answer:
11.2 inches.
Step-by-step explanation:
Applying the tangent/secant theorem:
9^2 = 5(y + 5)
5y + 25 = 81
5y = 56
y = 11.2 in.

Answer:
315
Step-by-step explanation:
z = a+bi
The modulus is the sqrt ( a^2 +b^2)
and the argument (I call it theta) is equal to arctan (b/a)
We have z = 3-3i
We are looking for the argument of z
theta = arctan (-3/3)
= -45 degrees
They don't like negative arguments so add 360 degrees to it. It is the same value, we just loop once around the circle.
-45+360 =
315
