Two sides of a triangle are: 5, 14. By triangle inequality the sum of each pair of sides must be > the third side. x + 5 > 14 Subtract 5 from both sides. x > 9
x + 14 > 5 Subtract 14 from both sides. x > -9
5 + 14 > x 19 > x
x has to be greater than 9 but less than 19. Letter A
I guess you mean 5m and 14m are the lengths of 2 sides of the triangle.
If the length of any side is equal or greater than the sum of the other 2 sides then you can;t make a triangle.
So for example 19 cannot the answer because 19 = 5 + 14 . No triangle can be formed with sides that measure. and 38 is greater than 14 + 5 so its cant be C.
2.54 cm in 1 inch......how many inches in 51.78 cm...
51.78 / 2.54 = 20.4 inches <==
or this way... 2.54 / 1 = 51.78 / x....2.54 cm to 1 in = 51.78 cm to x inches cross multiply (2.54)(x) = 51.78)(1) 2.54x = 51.78 x = 51.78 / 2.54 x = 20.4 inches <==
