Answer:

Step-by-step explanation:

pi < O < 3pi/2 --> cos O < 0.

sinO = - 12/13 --> cosO = -5/13

--> secO = - 13/5.

malishahzad789: pi < O < 3pi/2 --> cos O < 0 what do you call this step what did you do exaclty?please explain

brunoconti: because in this intervall both cosine and Sine are negative. just wanted to emphasise on it
