Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

Find the measure of angle 4 AND...… angle 7
zaharov [31]

Answer:

<4 = 126

<7 = 55

Step-by-step explanation:

Remark

There are only 2 answers to this question. <4 has one of them and <7 has the other one. <7 is acute. <2 is obtuse.

Givens

<2 = 55 degrees

Solution

<4 is the supplement of <2

Therefore <4 + <2 = 180                     A straight line has an angle of 180°

<4 + 55 = 180

<4 = 180 - 55

<4 = 125

So <7 is either 55 or 125. Since <7 is acute, it is 55 degrees but we have another way of proving it.

<4 + <6 = 180 degrees            Interior angles on the same side of the transversal are supplementary

125 + <6 = 180

<6 = 180 - 125

<6 = 55

<7 =<6                                    Vertically opposite angles are equal.

<7 = 55 degrees.

Find the measure of &lt; AED for m &lt; BEC = 96
Strike441 [17]
I wish you would of put a picture but with what you gave me. if the angle is a straight line then you would just set it up like 96+x=180 bc a straight line ='s 180 and den subtract 96 from 180 which is 84 so x would = 84 if the angle is a supp. angle but til there's not a picture this might be wrong.
But i hope this helps have a nice nite!
