If you convert 2/5 into a decimal which is 0.4 and multiply it by 100
you'll get 40 which means 2/5 is 40%
so 35% is less than 2/5
To remember the ratios, use the mnemonic sohcahtoa.
S = O/H
C = A/H
T = O/A
In this case, we want S, sin. The side opposite angle X would be 24. The hypotenuse is 26, so the ratio is 24/26. <span />
Rewrite the fractions so they have a common denominator
3/4 = 15/20
Now add:
4 15/20 + 7 11/20 = 11 26/20
26/20 simplifies to 1 3/10
11 + 1 3/10 = 12 3/10 total minutes
Set the bottom equal to 0
x - 8 = 0
x = 8
