The statements which are true are:
In Trigonometry, the Law of Sine relates the length of sides of a triangle to the angle of a triangle.
According to this law if a,b and c are the sides of a triangle and A,B and C respectively are opposite angles to the side.
Hence, we have:
i.e. we have:
This could also be given by:
Answer:
See below.
Step-by-step explanation:
The law of sines is usually written as a / sin A = b / sin b == c / sin C where a is the side opposite angle A ,etc.
The first equation is true because it is obtained by cross multiplying
a / sin A = b / sin B, therefore b sin A = a sin B.
The second one is not true.
The third and fourth are both true.
7 hot dogs, 4 wings
5 hotdogs, 5 wings
4H + 7W 《56
H = 7, W = 4
4(7) + 7(4) = 56《56
H = 5 , W = 5
4(5) + 7(5) = 55《56
