Answer:
A
Step-by-step explanation:
since 36=6² and the other option is not square of integer
3333334444444353553535354
X=2
Y=4
Multiply top so y values cancel out, so multiple top by -3. Y values cancel out. You combine top and bottom equations, x=2. Plug 2 in first equation for x. Y=4
Complementary angles add up to 90 so
angle + 47 = 90
angle = 90 - 47
angle = 43 so A
Answer:
-sin(2A)
Step-by-step explanation:
1-(sin(A)+cons(A))^2
1-(sin(A)^2+2sin(A)cos(A)+cos(A)^2) :use FOIL to get it
1-(1+sin(2A))
1-1-sin(2A)
-sin(2A)
