Determine (5,12,13) is a Pythagorean triplet or not

Answer»

QUESTION:

Determine (5,12,13) is a Pythagorean triplet or not??

To find:

The VERIFICATION of ( 5 , 12 , 13 ) is a Pythagorean triplet.

Given:

Hypotenuse = 13 cm

Height = 12cm

Base = 5cm

Concept:

we know that the Pythagorean triplet can be FOUND by using the formula

$h^{2} = p^{2} + b^{2}$

where ;

h = hypotenuse

p = height

b = base

Solution:

$13^{2} = 12^{2} + 5^{2}$

$13 = \sqrt{12^{2} + 5^{2}}$

$13 = \sqrt{144 + 25}$

$13 = \sqrt{169}$

$13 = 13$

Conclusion:

Here the LHS is equal to the RHS , so it is proved that the (5,12,13) is Pythagorean triplet...

Answer»

Answer:

The answer is +or -2 $\sqrt{6\\$

Step-by-step explanation:

As,

2X2 + kx + 3 = 0

Comparing the GIVEN equation with ax2 + bx + c = 0, we get,

a = 2, b = K and c = 3

As we know, DISCRIMINANT = b2 – 4ac

= (k)^2 – 4(2) (3)

= k^2 – 24

For EQUAL roots, we know,

Discriminant = 0

k^2 – 24 = 0

k^2 = 24

k = ±√24 = ±2√6

in the adjoining figure x and y are respectively two points on equal sides ab and ac of triangle abc such that ax =ay .prove that ec =ec

Answer»

ANSWER:

HELLO there !!

Given :-

AX = AY

In ΔAXC and ΔAYB ,

AX = AY [ Given ]

BC = AB [ Given ]

∠A = ∠A [ COMMON ]

ΔAXC ≅ ΔAYB [ SAS ]

Hence ,

XC = YB [ cpct ]
