WILL GIVE BRAINLEST ANSWER IF ANSWERED IN THE NEXT 24 HRS Express the complex number in trigonometric form. -5i

Step-by-step explanation:

If a complex number is z=a+ib, then the trigonometric form of complex number is

where, and , is called the argument of z, .

The given complex number is -5i.

It can be rewritten as

Here, a=0 and b=-5. lies in 4th quadrant.

So, the trigonometric form is

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
