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:
Unlike many other arts in western and central Africa, pottery typically is done by women. African potters were used for different purposes from decorative to culinary reasons. The pots were created differently depending on the origins of their different traditions and associated dietary and religious customs.
Answer:
loss of volatiles to the atmosphere
Explanation:
volatiles are the group of chemical elements and chemical compounds with low boiling points that are associated with a planet's or moon's crust or atmosphere. Examples include nitrogen, water, carbon dioxide, ammonia, hydrogen, etc.
Volatiles were accreted throughout the Earth’s formation, but Earth’s early accretion history was volatile poor.
The correct answer is A. Represent the ranges of sizes in living lemurs, though extinct lemurs included larger forms.
Explanation:
The mouse lemur and the indri are two different species of lemurs, this means as all lemurs they are primates and native to Madagascar (an island in Africa). However, in terms of size the two species differ greatly, the mouse lemur is the smallest lemur existing species as they size of thee lemurs is only about 11 inches and its weight is around 30 grams; on the other hand, the indri is the biggest species of lemur as the size of these lemurs is 27 inches and their weight is around 8 kilograms. Despite this, the indri is not the biggest lemur species that has ever existed as there is evidence in the past there were lemurs as big as modern gorillas.
