<span>The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2 =>
a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0
576 - 3c^2 = 0
- 3c^2 = - 576
c^2 = 192
c = 8√3

ANSWER



EXPLANATION
For real number 'a',

is true because we have to plug in 'a' for x.

This is also true because limit of a constant is the constant.

is false. The correct value is


is also true because we have to substitute 5 for x.

is also false
The limit should be

While going to the ice
skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the
ice skating rink,
Rosario
drives a distance of
120 miles in = (1/55) * 120
<span> = 2.18 hours</span>
The number of miles
per hour Rosario averages while coming back home = x
Total up and down
time taken by Rosario = 2.75 hours
Then time taken by
Rosario to come
back
home from ice
skating rink = (2.75 – 2.18) hours
<span> =
0.57 hours</span>
Then we can write
the equation as
x = 120/0.57
miles/hour
<span>
= 210.53 miles/hour</span>
<span>So the average speed
of Rosario while coming back home from ice skating rink is 210.53 miles per
hour.</span>
