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:


A. The spelling of the two words might be similar and some sounds might be the same.
Although it is possible for words in two different languages to have the same spelling and/or pronunciation, it is much more likely that they would be similar. Since, the languages are derived from the same root and belong to the same family, it would make sense that the words would be similar, if not exactly the same.
Answer: When magma cools, it hardens to form igneous rock. How they figure it out: They observe rock samples and explore the Simulation, finding different ways to make rock form. They model the formation of sedimentary rocks using hard candy, and view a video showing igneous rock formation as magma cools.
Explanation:
The larger particles (boulders, etc.) not broken down during transport in the glacier because of the slow speed of glacier and abrasion.
Explanation:
When a mountain glacier start moving from mountain towards valley it creates some sorts of landforms by following some methods like abrasion, attrition etc. Moraine formed as a depositional land form in front, back, parallel and side pf a glacier. It refers to the accumulation of sediments ranging from large boulders to small particles at the front or at the end of a glacier.
The large boulders do not break down in smaller partcles as the followed the process of abrasion where friction takes place between glacier and its valley floor. Unless and untill the collision between two large boulders occur the boulders would not broke down.
