and 
Step-by-step explanation:
Assume that the terminal side of thetaθ passes through the point (−12,5).
In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.
Using Pythagoras theorem:




Taking square root on both sides.

In a right angled triangle




In second quadrant only sine and cosecant are positive.

Answer:
option B: 31/4
Step-by-step explanation:
Given
-3/4, -2/3 , -7/12, -1/2...........
General formula for arithmeti sequence to find nth term is
a_n = a_1 + (n-1) d
first term a_1 = -3/4
We find out common difference 'd'
Lets find the difference of first two terms

common difference is 1/12
now we need to find 103rd term

First term is -3/4, d= 1/12
