Answer:
76%
Step-by-step explanation:
First parts right
75.7% i think maybe
The state government said it was the president of president
You can’t you have to take a picture of it then it tells you the answer
Take L.H.S sin2A+sin2B/sin2A-sin2B
= sin2A+sin2B/sin2A-sin2B
Put
[sinC+sinD = 2sin(C+D)/2cos(C-D)/2]
[sinC-sinD = 2cos(C+D)/2.sin(C-D)/2]
= 2 sin(2A+2B)/2 cos(2A-2B)/2 / 2 cos(2A+2B) sin(2A-2B)
= sin(A+B).cos(A-B)/cos(A+B).sin(A-B)
= sin(A+B)/cos(A+B) . cos(A-B)/sin(A-B)
= tan(A+B).cot(A-B)
= tan(A+B).1/tan(A-B)
= tan(A+B)/tan(A-B)
∴ Hence we proved sin2A+sin2B/sin2A-sin2B=tan(A+B)/tan(A-B)
C is the correct answer
C is the only option in which the original shaped can be multiplied and get another one.
explanation:
look at the dimensions of the original shape, 1x5x3
look at the dimensions of C,
2x10x6
multiply the original by 2 and the answer is C it is the only one that is consistant
