Answer:
A
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to find EF
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
EF² + DF² = DE² ← substitute values
EF² + 12² = 18², that is
EF² + 144 = 324 ( subtract 144 from both sides )
EF² = 180 ( take the square root of both sides )
EF = 
→ A

Answer: LAST OPTION
Step-by-step explanation:
The complex numbers shown have the form:
By definition, the distance can the distance of the complex number from the origin on the complex plane can be calculated with the formula shown below:
Substitute values of each option. Then:
1) 
2) 
3) 
4) 
(CORRECT OPTION)
I believe the correct answer from the choices listed above is the last option. The last option clearly describes the illustration of the construction of a perpendicular to a line from a point on the line where you start on a point in the line. Using an arbitrary radius, draw arcs intersecting the line <span> at two points. </span>
Hope this answers the question. Have a nice day.
