Question

Find the coordinates of the point on a circle with radius 15 corresponding to an angle of 220

Answer 1

(-11.5,-9.6)

Explanation:

The coordinates of a point on a circle with a radius of 15 corresponding to an angle of 220 can be found using the following formula:

`\tt x = r * cos(\theta)\\\tt y = r * sin(\theta)`

where:

• r is the radius of the circle (15)

• θ is the angle (220°)
• x is the x-coordinate of the point
• y is the y-coordinate of the point

Plugging in the values for and θ, we get:

x = 15 * cos(220) = -11.5 in nearest tenth

y = 15 * sin(220) = -9.6 in nearest tenth

Therefore, the coordinates of the point on a circle with a radius of 15 corresponding to an angle of 220 are (-11.5,-9.6).
