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.

Answer:
Option C.
Step-by-step explanation:
Given information: RSTU is a parallelogram, Digonals RT and SU intersect each other at point V, UV=(x-3) and VS=(3x-13).
According to the properties of a parallelogram, the diagonals of a parallelogram bisect each other.
Using the properties of parallelogram we can say that point V divides the diagonal SU in two equal parts, UV and VS.


Subtract x from both sides.

Add 13 on both sides.

Divide both sides by 2.

Therefore, the correct option is C.
Answer:
A) 11% B) 60
Step-by-step explanation:
(for A) if you add all the "Frequency" it adds up to 100, so we don't need to do any maths for that because we already have our 100% right there. So less maths to do because if that right there is already the whole, then the frequency of it is the % out of 100%
(for B) If you take your calculator and do 12 x 500, you get 6,000, press the "%" button and it gives you the percent of what that probability of getting 6 after rolling 500 times with its sent frequency
(took me a minute to learn this this for you... by that i mean i messed around with my calculator for like 3 minutes) Hope this is right.
