How can you visit the sun without burning up worksheet answer key is a heading for a worksheet that involves mathematical questions to calculate. The attached file displays those mathematical questions.
Before that, the sun is known as a star that is located in the middle of the Solar system. It is a virtually flawless sphere of hot plasma that has been heated by nuclear fusion processes in its center, thereby radiating energy as infrared radiation and ultraviolet light.
It is nearly impossible to visit the sun due to the degree of its temperature and radiation.
- From the image attached below which depicts the heading to the question, we have:
a) 5(x - 9) = 2x + 15
Open brackets
5x - 45 = 2x + 15
Collect like terms
5x - 2x = 45 + 15
3x = 60
x = 60/3
x = 20
b)
Open brackets
7n - 20 = 36n + 9
7n - 36n = 20 + 9
- 29 n = 29
n = - 29/29
n = - 1
Therefore, from the given information, we can conclude that It is nearly impossible to visit the sun due to the degree of its temperature and radiation. Also, the value of x = 20 and the value of n = -1

The height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.
<h3>What is right angle triangle property?</h3>In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.
Here, (b) is the opposite side, (a) is the base side.
Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.
The angle of elevation of the tree from one position on a flat path from the tree is
From a second position,
Farther along this path it is,
Let the distance between tree and first position is x. Thus, from the trigonometry,
....1
The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,
......2
Compare the equation 1 and 2,
Put this value in equation 1 as,
Thus, the height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.
