Let Susan's present age be x
Now, after 7 years ( her age will become 7 +x then) she'll be 2 as old she was 3 years ago.
Her age 3 years ago must be x-3
Now according to question,
twice Her age 3 years ago = her age after 7 years
now,
2(x-3) = 7+x
2x-6 = 7+x
2x-x =7+6
x = 13
x = 13
Therefore, her age presenr age is 13 years.

Step-by-step explanation:
cos ø=adjacent/hypotenuse
cos37°=17.3/hypotenuse
hypotenuse=17.3/cos 37°
hypotenuse=21.66
