Answer:
(146 + 0i)
Step-by-step explanation:
(11+5i)(11-5i)
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 11 + 5i) • ( 11 - 5i) =
(146 + 0i)

Answer:
x = 3
Step-by-step explanation:
To find the value of x. We have to use Exterior Angle Theorem.
It is says "The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle."
In the given figure,
45x = 25x + (57 + x)
Now let's find the value of x.
First we need to isolate the variable terms
45x - 25x = 57 + x
20x - x = 57
19x = 57
x = 57/19
x = 3
The value of x = 3.
Thank you.
