Answer:
which is also 1.4142
Step-by-step explanation:
To solve this the formula is...
| a+(b)i | =
which equals... ![\sqrt{a^2+b^2}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%2Bb%5E2%7D)
From the equation we know that a=1 and b=-1 because the "i" is negative
Plug in numbers...
Solve... you would get ![\sqrt{1+1}](https://tex.z-dn.net/?f=%5Csqrt%7B1%2B1%7D)
This equals ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Hope this helps!
Answer:

Step-by-step explanation:
pythagorean theorem
My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.
Answer:
<em>The value of x is 40°</em>
Step-by-step explanation:
The triangle described in the text of the question is shown in the image attached.
Note the angles x and 4x-20 are supplementary since they form a line. Thus:
x + 4x - 20 = 180
Simplifying:
5x - 20 = 180
Adding 20:
5x = 200
Solving:
x = 200/5 = 40
The value of x is 40°
