Let the length of unknown side be x
So, hypotenuse = 2x + 1
By pythagorean theorem ie , a² = b² + c²
(2x + 1)² = x² + 15²
4x² + 1 + 4x = x² + 225
3x² + 4x -224
(3x +28)(x-8)
x = -9.33 , 8
Since, length can't be negative
x = 8
∴Unknown side length = 8 m
Length of hypotenuse = 2 x 8 + 1 = 17 m
Hope it helps now.
You pass the x in one side and numbers to the other side
8x-5x=58-4
add and subtract
3x=54
divide by 3
x=18
36/96 x 100= 37.5% is the answer
Answer is -10
Step by step exploration
7x=-70
x=-70/7
x=-10
Answer:
Hence r=10.3 cms (rounded to tenth place)
Step-by-step explanation:
In Triangle KLN ,
KN = 5 Cms
LN = ½ of LM
As the Perpendicular dropped from the center to the chord bisects it.
LM = 18 cm
LN = 9 cm
Now we have to find r or KL
We apply Hypotenuse Formula in this
The formula is given as

Where c = r
a=5
b=9
Putting them in the formula
