Ah you just need to know how to set this question up.
Remember A^2 + B^2 =C^2
So use X as the length of one of the unknown sides.
X^2 + (x +14)^2 = 26^2
so you end up with 2x^2 +196 = 676
then solve it out
Hope that helps!

Given: c = 26 feet, hypotenuse of a acceptable triangle a = x, length of one leg b = x + 14, length of the different leg discover: lengths of the legs answer: utilizing the Pythagorean Theorem: c^2 = a^2 + b^2 (26)^2 = x^2 + (x + 14)^2 676 = x^2 + x^2 + 28x + 196 x^2 + x^2 + 28x + 196 = 676 2x^2 + 28x + 196 - 676 = 0 2x^2 + 28x - 480 = 0 Divide with the help of two both left and acceptable of the equations.... x^2 + 14x - 240 = 0 Factoring: (x + 24)(x - 10) = 0 Equate each binomial aspect to 0.... x + 24 = 0 x = -24 overlook this answer because it truly is detrimental. x - 10 = 0 x = 10 ANS the different leg is, x + 14 = 10 + 14 = 24 ANS teddyboy

Let x= length of the smaller side of a triagle and
x+14= lengh ofthe other side of a trianle
It is given that the hypotenuse of a right triangle is= 26
Using pythogorian theorm
c^2=a^2 + b^2
(26)^2= (x)^2 + (x+14)^2
676 = x^2 +x^2 +28x+ 196
2x^2 +28x+ 196 -676 =0
2 (x^2 +14x- 240) =0
on factoring (x^2 +14x- 240) =0 we get
(x+24) (x-10) =0
Therefore x= -24 and x=10
Neglect the negative sign, because lenth cannot be negative
Therefore x=10 is the answer
Hence one side is 10 unit and the other side will be 10+14=24units

Let x be the length of the short leg. Then the long leg is x+14 and (from Pythagoreas Theorem)
x² + (x+14)² = 26² so that
2x² + 28x -480 = 0
(2x - 20)*(x + 24) = 0 So
x = 10 and x = -24 are solutions
Negative length is an extraenous root, so the lengths of the sides are 10 ft. and 24 ft.

We have a right triangle which must form a pythagorean triplet as follows
(x,x+14,26)
So that 26^2 = x^2 + (x+14)^2
676 = x^2 + x^2 + 28x + 196
2x^2 + 28x -480 = 0
x^2 + 14x - 240 = 0
Factoring we get
(x + 24)(x-10) = 0
Which means our sides must be 10 and 24
x = -24 is not a valid solution since a length can not be negative
The the triplet is (10,24,26)

a = b + 14
c = 26
If this is a right triangle, then
a^2 + b^2 = c^2
(b + 14)^2 + b^2 = 26^2
((b + 14)(b + 14)) + b^2 = 676
(b^2 + 14b + 14b + 196) + b^2 = 676
b^2 + 28b + 196 + b^2 = 676
2b^2 + 28b + 196 = 676
2b^2 + 28b - 480 = 0
2(b^2 + 14b - 240) = 0
b^2 + 14b - 240 = 0
x = (-b ± sqrt(b^2 - 4ac))/(2a)
x = (-14 ± sqrt(14^2 - 4(1)(-240)))/(2(1))
x = (-14 ± sqrt(196 + 960))/2
x = (-14 ± sqrt(1156))/2
x = (-14 ± 34)/2
x = (-56/2) or (20/2)
x = -28 or 10
b = 10
a = 10 + 14 = 24
ANS : 24ft and 10ft

(leg1)^2 + (leg2)^2 = (hypotenuse)^2
or
a^2 + b^2 = c^2
leg1 = leg2 + 14 feet
or
a = b + 14
(b + 14)^2 + b^2 = 26^2
b^2 + 28b + 196 + b^2 = 676
2b^2 + 28b - 480 = 0
2(b^2 + 14b - 240) = 0
b^2 + 14b - 240 = 0
b = [-14 +/- sqrt( (14^2) - (4)(1)(-240)) ] / 2
b = [-14 +/- sqrt( (196 + 960) ] / 2
b = [-14 +/- 34 ] / 2
b = -24 or 10 feet
Since length cannot be negative, b = 10 feet
leg 2 = 10 feet
leg 1 = 24 feet

x^2 + (x + 14)^2 = 26^2
x^2 + x^2 + 28x + 196 = 676
2x^2 + 28x = 480
x^2 + 14x = 240
x^2 + 14x + 49 = 240 + 49 = 289
(x + 7)^2 = sqrt(289) = +/-17
x = 17 - 7 = 10
Check:
10^2 + 24^2 = 100 + 576 = 676 = 26^2
