Writing each complex number in exponential form makes this very easy. Recall Euler's formula:
Then
(since 45º = π/4 rad)
(since 165º = 11π/12 rad)
The product is
and in Cartesian form this is
Answer:
314 ft²
Step-by-step explanation:
Area of a circle is:
'r' is the raduis.
We are given the radius of 10 ft.
Using 3.14 for pi:
The area of the circle should be 314 ft².
Answer:
x=15°
Step-by-step explanation:
Given that Ray AB is the angle bisector of , then and given that , we equate the two angles to solve for x:
From the equation above, x=15°
Consider factors of 42, then if the factors can be added or subtracted.
42 = 42 * 1
42 = 21 * 2
42 = 14 * 3
42 = 7 * 6
Since none of these can be added or subtracted to equal 15, no intergers satisfy these criteria.
