Answer: A=20.8, B=20.5, C=10, D=2, E=12.6

Explanation: It takes time, but all you have to do it make an equation adding all the sides together, which equals 85.9. Then find “a” and plug that back in to each side. (I’m pretty sure this is right, but sorry if I’m wrong)

What is the complex conjugate of 13-21i?
irga5000 [103]

Answer:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i). This means that it either goes from positive to negative or from negative to positive.

As a general rule, the complex conjugate of <span>a+bi</span> is <span>a−bi</span>.

Therefore, the complex conjugate of <span>3−2i</span> is <span>3+2i</span>.

Hope this helped!!... :D

Please correct me if I'm wrong!!.. :3

Readme [11.4K]

The weight of the circle that is double the weight of the triangle is 20 grams.

<h3>How to find weight ?</h3>

The weight of the rectangle is 80 grams.

The weight of the triangle is double the weight of the  weight of the circle.

A rectangle is made up of 2 triangles. Therefore,

weight of each triangle = 80 / 2 = 40 grams

Since, the weight of the triangle is double the weight of the circle, the weight of the circle can be calculated as follows:

weight of circle = 40 / 2

Therefore,

weight of the circle = 20 grams.
