Ok so if they are similar that means equal angles so 50+70=120 then 180-120=60 so the answer is A. <span>#TeamAlvaxic</span>
To define a line segement you need 2 points (any 2 points because as long as you can draw a line between them) and then you must use capital block letters with a line on top for example if you have point A, and point B you wwoukd define it as AB with a line on top. hope this helps ;p
All are correct except C
You need to check: A, B and D
Hope it helps.
Answer: (no real solutions) but if its complex math it's:
x= 0.0000 + 5.0000
x= 0.0000 - 5.0000
Step-by-step explanation: Solve : x2+25 = 0
Subtract 25 from both sides of the equation :
x2 = -25
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ -25
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Accordingly, √ -25 =
√ -1• 25 =
√ -1 •√ 25 =
i • √ 25
Can √ 25 be simplified ?
Yes! The prime factorization of 25 is
5•5
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 25 = √ 5•5 =
± 5 • √ 1 =
± 5
The equation has no real solutions. It has 2 imaginary, or complex solutions.
Similar is when two figures are the same exact shape (with the same proportions), but they are different sizes and sometimes different orientation.
