Answer:
Option 3
Step-by-step explanation:
Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
![360\°/5=72\°](https://tex.z-dn.net/?f=360%5C%C2%B0%2F5%3D72%5C%C2%B0)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
Alright, lets get started.
The question says there are 18 pair of eyes staring at the monkey.
Usually 1 pair of eyes are consideed for 1 person.
It means , 18 pairs of eyes means 18 animals.
Means 18 animals are staring at monkey when it grabs the apple from unicorn's mouth.
This 18 animals includes unicorn itself because when monkey was grabing the apple from unicon's mouth, unicorn must be looking at him.
So, number of animals present at that time in forest : 18 animals(including unicorn) + 1 monkey itself
Means total 19 animals
Hence the answer is, 19 animals are in the forest in this moment : Answer
Hope it will help :)
Y = x² - 16
y = (0)² - 16
y = 0 - 16
y = -16
The y - intercept of the equation is -16.
