the hypothnue of right triangle is 2 more than twice of one ofthe other side while the 3rd side is 13 more than half of the hypothnue find the length of all the side
Answers
Step-by-step explanation:
Given :-
The hypothnue of right triangle is 2 more than twice of one ofthe other side while the 3rd side is 13 more than half of the hypotenuse.
To find :-
Find the length of all the sides ?
Solution :-
Let the one side of the right angled triangle be X units
Then the hypotenuse of the right angled triangle
= 2 more than twice of the one side of the triangle
= (2X+2) units
The length of the third side
= 13 more than half of the hypotenuse
= (2X+2)/2 + 13
=> 2(X+1)/2 + 13
=> X+1+13
=> (X+14) units
The lengths are X units , (2X+2) units , (X+14) units
We know that
By Pythagoras theorem
Hypotenuse^2 = 1st Side^2 + 2nd Side^2
=> (2X+2)^2 = X^2+(X+14)^2
=> (2X)^2+2(2X)(2)+2^2 = X^2+X^2+2(X)(14)+14^2
Since (a+b)^2 = a^2+2ab+b^2
=> 4X^2+8X+4 = 2X^2+28X+196
=> 4X^2+8X+4-2X^2-28X-196 = 0
=> 2X^2-20X-192 = 0
=> 2(X^2-10X-96) = 0
=> X^2-10X-96 = 0/2
=>X^2-10X-96 = 0
=> X^2+6X-16X-96 = 0
=> X(X+6) -16(X+6) = 0
=> (X+6)(X-16) = 0
=>X+6 = 0 or X-16 = 0
=> X = -6 or X = 16
X cannot be negative
X = 16 units
One side = 16 units
Hypotenuse = 2X+2
=> 2(16)+2
=> 32+2
=> 34 units
Third side = (34/2)+14
=> 17+13
=> 30 units
The measurements are 16 units ,34 units ,
30 units
Answer:-
The measurements of all the sides of the right angled triangle are 16 units , 34 units and
30 units
Used formulae:-
Pythagoras Theorem:-
In a right angled triangle,the square of the hypotenuse is equal to the sum of the squares of the other sides.
