Answer:
sin(x) = 
x = 16.26°
Step-by-step explanation:
First use Pythagorean theorem to find the length of the hypotenuse. Use 
. Since we know a and b we can plug in to find c. When we plug in we get: 
. When we solve this out we get 25 = c.
Now that we know the value of c, we also know sin(x) = 
. Using this we see that sin(x) = .
To get the exact degree value of x, take the inverse sin of :
which gives us 16.26020° rounded to 16.26°
So.. notice the picture below
and thus, we also know, that A = 51, thus
now, the height is just a value, it can't be negative, thus we can rule out -17, thus h = 6
and surely you'd know what the base is
Answer: 17.69 miles
Step-by-step explanation:
Activity time (hours) :
Activity - - - - - - - - - - - - - time (hours)
Hiking - - - - - - - - - - - - - - - - - - - - 3
Mountain biking - - - - - - - - - - - 1.45
Horseback riding - - - - - - - - - - 1.2
Cross-country skiing - - - - - - - - 0.75
Average speed = 12.2 miles per hour.
How many miles did Brian bike?
Recall;
Speed = distance ÷ time
Distance = speed × time
Speed = 12.2 mi/hr
biking time = 1.45 hours
Distance (mountain biking) = 12.2 × 1.45 = 17.69 miles
Answer:
The side length is irrational
Step-by-step explanation:
Because the square root of 23 or 20+3 is a non-perfect square root and it's a never ending decimal.
