Add the numbers together then x 8 and you have your answer
ACD,DCE. 1 and 8, 6 and 7
Answer:
720 = x +133+138+148+95+105
x = 101
This equation is in standard from unless you mean vertex standard form?
Sin (Π/2 - theta) = sin(Π/2) * cos(theta) - cos(Π/2) * sin (theta)
and as we know sin(Π/2) =1 , cos(Π/2)=0
so sin(Π/2 - theta) = 1* cos(theta) - 0* sin(theta)= cos(theta)
2nd cos(180+ theta) = cos(180)*cos(theta) - sin(180)* sin(theta)
,,, so , cos(180+theta) = -cos(theta)
