Answer:
The reference angle is
Step-by-step explanation:
The given angle is
The reference angle is the acute angle, that a given angle makes with the x-axis.
First let us make a sketch of the given angle. <em>See diagram in attachment.</em>
Let be the reference angle of
Then, from the diagram, we need to subtract from
to get to
.
We can therefore write the following equation and solve for .
We group like terms to get,
We collect LCM to get,
We simplify to get,
We divide through by
to get,
The correct answer is D.
The shape of the vertical cross section of the solid figure is Circle , Option A is the right answer.
What is a Circle ?
A circle is a round figure with all the points lying in the same plane .
It is given that
Tung rotates a square around its horizontal axis of symmetry to make a solid figure.
the shape of the vertical cross section of the solid figure will be a circle that can be seen in the image attached
The rotation image is also attached and the horizontal axis is taken as straight to show the formation of a circle.
Therefore Option A is the right answer.
