what is the sum of the complex numbers 6+2i and 3+5i, where i=sqrt(-1)

Answers

Answer 1

Answer:

The sum of the complex numbers is [tex]9+i\,7[/tex].

Explanation:

Let be [tex]u = 6 + i\,2[/tex] and [tex]v = 3 + i\,5[/tex], the sum of the complex number can be found by algebraic means. That is:

1) [tex]u = 6 + i\,2[/tex], [tex]v = 3 + i\,5[/tex] Given.

2) [tex]u+v = (6+i\,2)+(3+i\,5)[/tex] Definition of addition.

3) [tex]u+v = (6+3) + (2\,i + 5\,i)[/tex] Commutative and associative properties.

4) [tex]u+v = 9 + (2+5)\,i[/tex] Definition of addition/Distributive property.

5) [tex]u + v = 9 + i\,7[/tex] Definition of addition/Commutative property/Result.

The sum of the complex numbers is [tex]9+i\,7[/tex].

C)

x = 50

D)

x = 130

Answers

It would be Option A. x=65°

Answer:

x= 65°

Explanation:

2 sides are equal so the angles opposite to them are equal

it is isoceles triangle

total angle of triangle is 180°

50° + x° + x° = 180°

50° + 2x = 180°

2x= 180°- 50°

x= 130°/2

x= 65°
