Step-by-step explanation:
<u>Substitute f(0) into the function:</u>

<u>Include exponent:</u>

<u>Multiply:</u>

First lets figure out what -5+5 equals. so -5+5=0. so then -4-0 equals -4. so therefor your answer is -4
It is a straight line, which is 180°
You have "missing angle" + 24° = 180°
Answer is 156°
Just subtract 4 each time.
