<h2>1</h2>Step-by-step explanation:
Magnitude of an earthquake is defined as
. Here
is the Intensity of the earthquake and
is the intensity of standard earthquake.
We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as .
10 times more intense than standard earthquake ⇒
Magnitude of the earthquake =
∴ Magnitude of the earthquake is 1.
The angle of rotation of triangle ABC to A'B'C is 105°
<h3>How to illustrate the information?</h3>It should be noted that the rotation from ABC to A'B'C is in a clockwise direction.
Point B is also on the x axis and point B' is in the second quadrant.
In this case, the angle that depicts the second quadrant is 105°.
In conclusion, the correct option is D.
The complete question is:
