Answer:
Maybe ordered pair
Step-by-step explanation:
I'm guessing you meant like what is it called
Seeing as this is a right triangle, we would solve for the unknown angle using a trigonometric function.
Remember! SOH-CAH-TOA
Looking from the unknown angle, we are given the adjacent side and the hypotenuse. Therefore, we should use the cosine function.
cos(?) = 17 / 19
---To find the unknown angle measure, you will need to use the inverse cosine function. This function is generally found by using the "2nd" button on your calculator and then pressing the cosine button. It should look like one of the following options: "cos^-1" or "arccos".
Make sure your calculator is in degrees, not radians!
cos^(-1) [17/`9]
26.52
---Round to the nearest degree per the instructions
Answer: 27 degrees

Answer:
Step-by-step explanation:
One day cost $18.50
So
Number of days * 18.50 = total cost
Answer:
20.8
Step-by-step explanation:
The chord with length x is bisected by the perpendicular segment.
Use the Pythagorean theorem to find the length of half of x.
Let's call half of x, y.
y^2 + 6^2 = 12^2
y^2 = 144 - 36
y^2 = 108
y = sqrt(108)
x = 2y = 2sqrt(108)
x = 20.8
