Step-by-step explanation:
the ratio of sides of a 30-60-90° triangle, respectively, are 1 :
: 2
we can solve for 'x' using this proportion:
x/4 = 1/
now cross-multiply:
x = 4
x = 4/
we don't want to leave a radical in the denominator so we can multiply numerator and denominator by
to get:

/ 3 or 

The answer is the last one listed...

80% = 6 in
100%=?
100/x 80/6 (proportional relationship)
then cross multiply
600 = 80x
600/80= 7.5
x=7.5
2.6C + 1.8C + 2.75 =
4.4C + 2.75
