Question

Can anybody help me on this?

Answer 1

Answer:

length = 62.41 inches

Step-by-step explanation:

Using pythagoras theorem -

Let

a = hypotenuse

b = height

c = length

a^2 = b^2 +c^2

75^2 = 41.6^2 + c^2

Therefore,

75^2 - 41.6^2 = c^2

5625 - 1730.56 = c^2

389.44 = c^2

square root (389.44) = c

62.40544848 = c

Answer 2

Answer:

62 inches.

Step-by-step explanation:

• We need to use the Pythagorean theorem to solve this problem. If the diagonal of the screen is 75 inches, and the height is 41.6 inches, then these values represent B and C. We need to find the value of A, the length of the TV. Since $A^{2} + B^{2} = C^{2}$, all we have to do is
• square 75, which gives us 5625
• then subtract the value of 41.6 squared (1730.56)

and finally, take the square root of the number we are left with after subtracting $B^{2}$ , or 1730.56, from 5625, or $C^{2}$

5625 - 1730.56 =3894.44

$\sqrt{3894.44}$ = 62.405
