Answer:

$\huge\boxed{c)\ 15,\ 36,\ 39}$

Step-by-step explanation:

$\text{Let}\ a\leq b\leq c\ \text{the sides of the triangle}.\\\\\text{If}\ a^2+b^2=c^2\ \text{then a triangle is a right triangle}\\\\\text{If}\ a^2+b^2c^2\ \text{then a triangle is a acute triangle}$

$a)\ 28,\ 45,\ 53\\\\28^2+45^2=784+2025=3593\\53^2=2809\\\\28^2+45^2>53^2\to\text{acute triangle}\\\\b)\ 17,\ 22,\ 29\\\\17^2+22^2=289+484=773\\29^2=841\\\\17^2+22^2$

( 97 )^2 evaluate of the following by using identities

Neko [114]

Answer:

9409

Step-by-step explanation:

Let's rewrite 97 as 100 - 3.

Identity used :

(a - b)² = a² - 2ab + b²

Now, evaluating the expression :

⇒ (100 - 3)²

⇒ (100)² - 2(100)(3) + (3)²

⇒ 10000 - 600 + 9

⇒ 9400 + 9

⇒ 9409
