Sin x cos x = -cos x<br> Find all angles that satisfy the equation below
n200080 [17]

Answer:

x=90^\circ,270^\circ

Step-by-step explanation:

sinxcosx=-cosx

sinxcosx+cosx=0

cosx(sinx+1)=0

cosx=0

x=90,270

sinx+1=0

sinx=-1

x=270

Therefore, the angles that satisfy the equation are x=90^\circ,270^\circ
