Answer:
Step-by-step explanation:
Since this is a 30-60-90 triangle, we need the Pythagorean triple for such a triangle. the side length across from the 30 degree angle is labeled as x, the side across from the 60 degree angle is x√3, and the hypotenuse is 2x. Since we know the side length of the side across from the 60 degree angle, we use that identity and solve for x:
and
and rationalizing the denominator,
This is the side length of the side across from the 30 degree angle. In order to find the hypotenuse, we have to multiply this value by 2 to get
12√3, the third choice down.
6 - 2x = 0
- 2x = -6 *(-1)
2x = 6
x = 6/2
x = 3

<u>Answer</u>:
A regular polygon first maps directly onto itself after rotating 20 degrees has 18 sides
<u>Explanation</u>:
Given:
Angle rotated=20 degrees
To find:
Number of sides the polygon has=?
Solution:
RESULT:
Hence the number of sides the polygon has =18
I would say C because it does not have a 90° angle, but the rest has at least 1 90° angles.
1. 24/(63%-59%)= 24/4%= 6,so the phone drop one charge every 6 minutes of listening to top pop.
42/6=7(the percentage consumed in 42 minutes)
46%-7=39%(percentage of battery left)
2. 76%-16%=50%(percentage of battery consumed after watching 3 episodes of "the haunted cave")
80x100%=8.000%(maximum percentage of battery at which the phone can be charged 80 times)
8000%/50=160(episodes of "the haunted cave" the monkey can watch)
3.idk the answer, sorry
