Alright, lets get started.
Please take a look at the diagram attached.
The reference angle of 75 will be 75
As it is mentioned that the angle intersects the unit circle means r = 1
So, finding cos
cos 75 =
cos 75 =
cos 75 = 0.259 is the Answer
Hope it will help :)
Answer:
Option D. 2.51 is correct.
Step-by-step explanation:
Magnitude of first earthquake = 8.6
Let intensity of first earthquake be x
Magnitude of second earthquake = 8.2
Let intensity of second earthquake be y
Now, to find the factor by which intensity of first earthquake is greater than intensity of second : we divide equation (1) by equation (2)
Hence the required factor is 2.51
Therefore, Option D. 2.51 is correct.
