Answer:
31.1
Step-by-step explanation:
This is an isosceles triangle. Let us name the unnamed side y. y will also equal 22. We also know that this is a right triangle so using the pythagorean theorem we can calculate x. x = √(22^2+22^2) so x = 31.1.

Answer:16.110
Step-by-step explanation:
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.
