Which graphs have rotational symmetry? Check all of the boxes that apply.
ivanzaharov [21]

Answer:

The correct option are;

On a coordinate plane, a cubic function has an x-intercept of (0, 0)

On a coordinate plane, an oval is in quadrant 1

Step-by-step explanation:

Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape

For a cubic function that has x-intercept = (0, 0) we have;

y = f(x) = a·x³ + b·x² + c·x

Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°

The shape of an oval looks the same when rotated through 180°

What is the value of x?
charle [14.2K]

Answer:

72

Step-by-step explanation:

RQS + KLM = 180 degrees, because RQS = QLK, and QLK + KLM = 180 degrees (because they are on the same line).

Substitute the values for RQS and KLM:

x-36 + x = 180 -->

2x-36=180 -->

2x = 144 -->

x=72
