Answer:
x=-3 and y=-3
Step-by-step explanation:
add the two equations, so 6x-6x, -6y-3y, and 0+27 to get -9y=27. y ends up equaling -3. plug negative 3 into the either of the equations and solve for x, which ends up being -3

Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA
Answer:
1152 inches of fringe
Step-by-step explanation:
l multiplies with width to get the area so
w is one half of 48 which 24
so 24x48 which is 1152 inches of fringe
