Hi my lil bunny!

Lets do this step by step.
This is the trigonometric form of a complex number where
is the modulus and
is the angle created on the complex plane.

The modulus of a complex number is the distance from the origin on the complex plane.
where 
Substitute the actual values of a = -5 and b = -5.

Now Find
.
Raise - 5 to the power of 2.

Raise - 5 to the power of 2.

Add 25 and 25.

Rewrite 50 as 5^2 . 2 .

Pull terms out from under the radical.

The angle of the point on the complex plane is the inverse tangent of the complex portion over the real portion.

Since inverse tangent of
produces an angle in the third quadrant, the value of the angle is
.

Substitute the values of
and
.

Hope this helped you.
Could you maybe give brainliest..?

Not direct answer but
this is how I think
radius = 4 so AC is also 4
You can find with this
2π ( 4 ) ( 51°/360°) = Answer
Actually I am lazy to calculate (◔‿◔)
Answer:
3/5
Step-by-step explanation:
So basically "in" is dividing so you have to divide
1/2 / 5/6 = 3/5
Answer:
18
Step-by-step explanation:
one half times (four plus eight)
Writing mathematically
1½ ( 4+8)
Using BODMAS
we'll take the bracket first
1½ × 12
Change 1½ to improper fraction = 3/2
3/2 × 12 = 3×6
= 18
