Answer:

Ellipse

Explanation:

Given


x = 7sin\theta


y= 2cos\theta

Required

The kind of shapes with such equations

This answer to this question is(B) Ellipse

The parametric equation of an ellipse is represented as:


x = asin(\theta) and
y = bcos(\theta)

In this case:


a=7\ b = 2

So:


x = 7sin\theta and
y= 2cos\theta
