Answer: 
Explanation:
We have a right triangle with sides AB, BC=5cm and AC=13cm (the hypotenuse). Let's apply the Pithagorean Theorem to find AB:
(1)
(2)
(3)
(4)
Now that we know the value of each side of the triangle, we will use the trigonometric function sine to find the angles C and A (angle B is
remembering we are talking about a right triangle):
For angle C:

(5)
(6)
(7)
For angle A:
(8)
(9)
(10)
Calculating the difference between both angles:


The major difference between Earth and the other planets in our solar system is that Earth has an atmosphere. The atmosphere is the reason why Earth is livable place.
Answer:
The role of pricing on customer satisfaction has been largely ignored, however hospitality services are, for the most part produced by humans, and consequently, no two guest stays will be precisely alike.

Which makes it difficult to know customer satisfaction.
Meaning the relationship between the level of service and the price of hotel room is uncertain because know two human is alike.
