Answer:
<h2><u><em>Acute isosceles triangle</em></u></h2>Step-by-step explanation:
What type of triangle is shown in the image?
A triangle with two sides that are each eight units, and one side that is five units. Two angles are seventy degrees, and one angle is forty degrees.
Acute scalene triangle
Obtuse scalene triangle
<h2><u><em>Acute isosceles triangle</em></u></h2>Right isosceles triangle
The product of a <em>complex</em> number and its conjugate is (a + i b) · (a - i b), where a and b are <em>real</em> numbers, and the result for the <em>complex</em> number 2 + i 3 is 13.
<h3>What is the multiplication of a complex number and its conjugate</h3>Let be a <em>complex</em> number a + i b, whose conjugate is a - i b. Where a and b are <em>real</em> numbers. The product of these two numbers is:
(a + i b) · (a - i b)
Then, we proceed to obtain the result by some algebraic handling:
a · (a + i b) + (- i b) · (a + i b)
a² + i a · b - i a · b - i² b²
a² - i² b²
a² + b²
If we know that a = 2 and b = 3, then the product of the complex number and its conjugate is:
