You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
Answer:
I would say the TRIANGLE because it has none of the lines that a symmetry has.

The number in polar form is 
.
Step-by-step explanation:
A complex number is represented by elements of the form 
, for all 
, 
. The first part of the sum is the real component of the complex number, whereas the second part of the sum is the imaginary component of the complex number. The real component is located on the horizontal axis and the imaginary component on the vertical axis.
Now we proceed to present the point on the graph: (
, 
) We kindly invite you to see the result in the image attached below.
The polar form of the complex number is defined by:
(1)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number, measured in radians.
The magnitude and the direction of the complex number are defined by the following formulas:
Magnitude
(2)
Direction
(3)
If we know that and , then the polar form of the number is:
The number in polar form is .
Answer:
7x + 15y
Step-by-step explanation:
4x+ 3 ( 5y + x)
Step 1: remove the brackets by multiplying 3 with (5y + x)
4x+ 15y + 3x
Step 2: add the 4x and 3x
7x + 15y
1, because when you multiply 52 and 4 (the number of sides) to get the total square feet of the ceiling, you get 208 square feet, which is exactly how much 1 can of paint will cover
