Answer:
‘Of’ signifies multiplication. So, multiply 1/3 by 15, which gives you 15/3, which is 5.
C the fried plus the hamburger add up to $7
Sin 2A + sin 2B = 2sin(A+B) cos(A-B)
sin 2A - sin 2B = 2cos(A+B)sin(A-B)
dividing both...
(2sin(A+B) cos(A-B)) / (2cos(A+B)sin(A-B))
= (sin(A+B)cos(A-B))/(cos(A+B)sin(A-B))
=tan(A+B) X cot(A-B)
=tan (A+B) / tan(A-B)
