Answer:
The value found is.
sin θ = 0.6
Step-by-step explanation:
We know that the value of cosθ is given -4/5
cosθ = -4/5
First, lets finds the angle θ by taking inverse of cosine of -4/5
θ = cos⁻¹ (-4/5)
θ = 143.13°
Substitute the found θ = 143.13° it in tanθ to see if satisfies the equation tanθ < 0:
tanθ < 0
tan(143.13°) < 0
-0.75 < 0
Hence the equation is satisfied.
Which means that θ is equals to 143.13° and can be used to find sinθ
sinθ = sin 143.13°
sin 143.13° = 0.6
The older brother was born three years before the young one, which means that their age will always differ by 3. Don't be fooled by the fact that, in this particular year, the age of the older brother is exactly twice the age of the younger! This is not a property that will be carried on with the years: for example, next years bother A will be 4 and brother B will be 7, and 4 is not half of 7!
So, since the property that remains constant is the three year gap, when brother B (the older one) will be 60 years old, brother A will be 3 years younger, as always, which means that he will be 57.

Answer:
Find out how much is 1
Multiply 1/2 by 2 to get 1 and multiply 14 by 2 so the ratio is equal
1/2 x 2 = 1
14 x 2 = 28
so 1 = 28
Multiply everything 28
I'm pretty sure I have it in order clockwise
3/14 x 28 = 84/14 = 6/1 = 6
1/14 x 28 = 28/14 or 2
5/7 x 28 140/7 = 20
3/7 x 28 = 84/7 = 12
2/7 x 28 = 56/7 = 8
1/7 x 28 = 28/7 = 4
3/4 x 28 = 84/4 = 21
1/4 x 28 = 28/4 = 7
I'm guessing the middle would be 1 is 28
Hope this helps
