Find the polar coordinates of the points with cartesian coordinates (−x, y).

1 answer:

4 0

The relationship to go from Cartesian coordinates to polar coordinates is given by the following equations:

x = r * cos(theta)
y = r * sin(theta)

Since the coordinates we are given are just variables that can take <em>any </em>value, we'll have to work with that. Thankfully, that means we can just plug in these equations to get polar coordinates!

(-x, y) becomes
(-(r * cos(theta)), r * sin(theta))

The angles of a triangle are 80º, 2x + 2º, and 5xº. What is the value of x?

Gekata [30.6K]

Since the sum of the angles of a triangle = 180°

Then <span>80º + (2x + 2)º + 5xº = 180</span>°
82° + (7x)° = 180°
(7x)° = 180° - 82°
x = 98° ÷ 7
∴ x = 14

Answer:

110

Step-by-step explanation:

you place 30 in the place of X, and it becomes 4×30-10. in PEMDAS, multiplication goes first and 4×30=120. 120-10=110
