Present age of Justin=14
Present age of Sam=11
<u>Step-by-step explanation:</u>
Let the present age of Sam=x
Given that Justin is 3 years older than Sam
present age of Justin=x+3
Age of Sam 3 years ago=x-3
Age of Justin two years hence=x+3+2=x+5
given that after 2 years Justin's age will be twice that of Sam's age three years ago
therefore
Present age of Sam=x=11
Present age of Justin=x+3=11+3=14

Step-by-step explanation:
The building will be making 90° with the ground/horizontal.
Then we can apply Pythagoras theorem.
(Base)² + (Height)² = (Hypotenuse)²
=> x² + (12 foot)² = (37 foot)²
=> x² = (37 foot)² - (12 foot)²
We can expand LHS using a² - b² = (a + b)(a - b)
=> x² = (37 + 12 foot)(37 - 12 foot)
=> x² = 49 * 25 foot²
=> x² = (7 * 5)² foot²
=> x = 7 * 5 foot
=> x = 35 foot.
