A A A​

Answer 1

The missing number (?) is "249".

Step-by-step explanation:

In figure 1,

$(2^{2} +5^{2} )-3^{2}=(4+25) - 9 = 20$

In figure 2,

$(6^{2} +9^{2} )-10^{2} =(36+81)-100=117-100=17$

Similarly,

In figure 2,

$(12^{2} +13^{2} )-8^{2} =(144+169)-64=313-64=249$ = ?

The missing number (?) = "249".

Answer 2

Answer:

The missing number in the third triangle is 249.

Step-by-step explanation:

In the first triangle,

(2² + 5²) - 3² = (4 + 25) - 9 = 20

In the second triangle,

(6² + 9²) - (10)² = (36 + 81) - 100 = 17

In third triangle,

[(12)² + (13)²] - (8)² = (144 + 169) - 64 = 249

Therefore, missing number in the last triangle is 249.
