Answer:
• let's first get the percentage decrease:
• then multiply the percentage decrease with the mass given:
It is A, because a direct proportion follows the rule y=kx, and in A, k = 12 and it works for all of the x and y values
Sin 30 = 1/2
tan 45 = 1
Cosec 60 = 2 / √3 = 2√3 / 3
cot 45 = 1
Cos 60 = 1/2
sec 30 = 2 / √3 = 2√3 / 3
_______________________________
[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>
The face and denominator of the fraction are exactly the same thus the answer is 1 .
