Answer:
There are 7 sides.
Step-by-step explanation:
Let's Use the formula that states that the sum of the angles of an n-sided polygon is given by.
S=(n−2)180
Since we are given that the two angles are right, the angles and each of the remaining angles is 144.
And Therefore, the sum is:
S=90
(n−2)144
(n−2)180
=90
+90
+(n−2)144
⇒(n−2)180
−(n−2)144
=180
⇒(n−2)(180
−144
)=180
⇒(n−2)(36
=180
⇒n−2=
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
5=-7s
5/-7

Answer:
someone had the same exact question i just helped him on it sub 4 for x and 1 for h
Step-by-step explanation:
4x^2-5x-14 is your answer :)
He would change his tires a total of 4 times.
You divide the numbers like so:
160,000/40,000=4
