Answer:

5/hypotenuse, the square root of 7/ leg

Step-by-step explanation:

3^2+4^2=25 or 5^2. you use a^2+b^2=c^2. it would be one of the hypotenuses. If the missing number is a leg, you would do 4^2=3^2+x^2. 16=9+x^2, 7=x^2, so you plug in the numbers differently.

<h2><em><u>Solu</u></em><em><u>tion</u></em><em><u> </u></em><em><u>:</u></em></h2>

Let the third side be = x

Case 1. Find it if it's the hypotenuse.

Solution : Pythagoras Theorem = (H)²=(P)²+(B)²

= On substituting the values = (n)²= 4²+3²

= x²=16+9

= x²= 25

= x=√25

= x = 5

Case 2 . Find it if it's one of the legs

= If it is one of the legs , then the longest side of them will be the hypotenuse which is 4.

Legs = 3,n

Hypotenuse = 4

Pythagoras Theorem = (P)²+(B)²=(H)²

= 3²+x²=4²

= 9+x²= 16

= x²= 16-9

= x²= 7

= x= √7

= x = 2.64 (approx.)

ICE Princess25 [194]

Answer:

C

Step-by-step explanation:

{x}^{2}  + 5x + 8 = 4 \\  =  >  {x}^{2}  + 2 \times  \frac{5}{2}  \times x +  \frac{25}{4}  +  \frac{7}{4}  = 4 \\  =  >  ({x +  \frac{5}{2} }^{2} ) +  \frac{7}{4}  = 4 \\  =  > ({x +  \frac{5}{2} }^{2} ) =  \frac{9}{4}
