It's a 3 4 5 triangle so it's 20, no calculations needed.

Observe that 15 and 25 are multiples of 5 and make two sides of a 3,4,5 right angled triangle so the remaining side is 4x5=20

Or you could just understand it’s a 3 4 5 triangle scaled up. Becomes pretty simple after that.

No. Univertsity math is to see 3:4:5 triangle. One step 20

This is typical math-bullshit that works only in some combinations. Doesn't work vor 3 instead of 15 and 5 instead of 25 (result should be 4).

3-4-5. No pen needed. 3 sides are 15-20-25

Ph.D. math: 15=5x3 25=5x5 Solve for a smaller triangle with side=3 and hypotenuse=5. The other side is therefore=4. Multiply by 5. The answer is 20. All in your head. 3 seconds.

has nothing to do with university. It's simple Pythagorean theorem and difference of squares

Suppose Pythagoras had died of diarrhea as a child, and no one else had ever discovered his theorem; Then we would have to solve this problem the following way... As a side note: In universities, usually professors tend to emphasize on std methods over quick shortcuts or tricks.

Or you could just accept it’s a 3,4,5 triangle!

Here university maths was more like this: "Let's assume x=20. Now let's proof it. yada yada ya. trivial. lets skip one or two steps and then we have it. q.e.d" Me:😵‍💫

وأنا أشرحها لك بالطريقة السعودية 1-إذا مقابل الزاوية 90 غير معلوم قم بتربيع الضلعين ثم اجمعهم ثم اجذرهم 2- إذا ضلع غير مقابل 90 مجهول ربع الضلعين وقم بطرحهم ثم جذرهم هذي طريقتي السعودية وأتحدى فيثاغورس أو أي جامعة أسرع من هذه الطريقة
