Answer:
Your answer is 4 :)
Step-by-step explanation:
This is because 5 ( the length of the hypotenuse for the small triangle) times 3 equals 15 (the length of the hypotenuse for the bigger triangle). It's only natural that you would find x times 3 equals 12. x(4) times 3 equals 12
therefore 4 is your answer :) I hope I helped, and gosh I love triangle problems like this xD

Now we have to,
→ prove that 100 - [5 × (3 + 4)] = 65.
Let's solve the problem,
→ 100 - [5 × (3 + 4)] = 65
→ 100 - [5 × 7] = 65
→ 100 - 35 = 65
→ 65 = 65
→ LHS = RHS
Hence, proved the equation.
