To solve this question you need to set up the equation and simplify
x^2 +121 = 0     you need to get the x^2 by itself so subtract 121
x^2 = -121   Now take the square root of both sides. but you can;t take the square root of a negative number which is where the i comes into play. 
 x= + -  11 i

What is the medium of 14.1,20.7,24.3,16.0,20.8
bekas [8.4K]
To find the median of the numbers you’ll have to find the middle of the numbers.
So,you order them least to greatest:
14.1, 16.0, 20.7, 20.8, 24.3

If you search the number in the middle, the number would be 20.7 is the middle or median

Hope this helps! ;)

Writing a Two-Column Proof
Ludmilka [50]
For the blank on the left, the answer is "angle ABC" without quotes of course. This is because we're using the substitution property which is the reasoning for statement 4. To elaborate, we connect statement 1 and statement 3 to get to statement 4.

The last statement, statement 5, is simply a repeat of the claim we want to prove. So you'll just copy/paste where it says "prove" as your last statement. Always start with the "given" and end up with "prove" is how I think of it.

The reasoning for the last statement is "definition of congruence". If two angles are congruent, then they have the same angle measure.

The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below:
topjm [15]
Basic facts of trigonometry

sine, cosine, and tangent will give you the proportion of the sides of a right triangle in relation to an angle

sin x = opposite side/ hypotenuse
cosx= adjacent side/ hypotenuse
tan x= opposite side/ adjacent side

x is our angle
hypothenuse is the longest side of the right triangle

a good way to memorize this is SOH CAH TOA

now since your picture is not given, I will make some assumptions, such as the hypothenuse is the distance from the sun to the moon.

since you want to find the distance from the earth to the sun, and you know the distance from the earth to the moon, this means on a right triangle, you're trying to find the relationship between the adjacent, opposite side, and an angle

which means you will want to use tan x= opposite side/adjacent


now, i cant go any further because the location of the angle is important in the explanation, but short answer,

sin,cos,tan of an angle will give a proportion of the sides. if you know the measurement of a side, you can use this proportion in order to determine the corresponding measurement of the other side
