The answer is C.

This is because 7 must be greater than 12-g.

G cannot equal 5 and below because 12-5=7.

Therefore C is the only answer that works.

Find the product of the given complex number and its conjugate.<br> 1/5+4i
nasty-shy [4]

Answer:

-15.96

Step-by-step explanation:

A conjugate is a binomial with the sign inside changed. So the conjugate of (1/5 + 4i) is (1/5 - 4i)

Set the original and the conjugate next to each other and F.O.I.L. Multiply the first numbers of each binomial, the 1/5 and the 1/5 to get 1/25. This is the "F."

Multiply the outer members, the 1/5 and the 4i to get - 60i. This is the "O."

Multiply the inner  numbers  ( the + 4i and the 1/5) to get + 60i. This is the "I."

Multiply the positive 4i and the negative 4i to get 16i squared

The positive 60i and the negative 60i cancel each other out.

The i squared changes into - 1. This makes the 16 negative.

Add 1/25 to - 16 to get - 15.96

If you cannot see my apologies, but you can zoom in!
nataly862011 [7]

Answer:

C

Step-by-step explanation:

The sum of the angles is 90

2x + x = 90

3x = 90

x = 30

the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees
