Answer: 144°
Step-by-step explanation:
It is a regular pentagon which means all five sides are the same length. This also means that the angle between any two adjacent vertices is the same. So to find the angle between two adjacent vertices we take 360° and divide it by 5 which equals 72°. But A and D are not adjacent to each other, they have E in the middle (it also has B and C in the middle on the other side, but that's the bigger angle, and we usually label angles through their smaller angle. ex: a 30° angle is 30° if you look at it on the smaller angle (∠ ← here), but if you look at the bigger side of the angle (here →∠) it is 330°, yet we still call it a 30° angle). So, between A and D are two equal angles A to E, and E to D. So we multiply 72° by 2 which equals 144°.
So the answer is 144°.
Answer:
4.2
Step-by-step explanation:
The term polynomial comes from the words poly- which means "many" and -nomial meaning "terms". In mathematics, a polynomial is an expression that consists of variables and coefficients wherein it only utilizes addition, subtraction, multiplication and a non-negative integer. In the given options above, the variable expression that is not a polynomial is option C. x^9+y^3.
The correct answer is option B
Answer:
We can do 220 jumping jacks in 5 minutes.
Step-by-step explanation:
We are given the function:
<u><em>Note: Considering there is typing mistake and the function is: j(x)=4x</em></u>
where x is minutes
We need to find How many jumping jacks can you do in 5 minutes.
So, here x=5
Now putting value of x in the given function
So, we can do 220 jumping jacks in 5 minutes.
