Answer:

{5,16,21}

Step-by-step explanation:

sides of triangle: the sum of every two sides must be greater than the third sides.

{14,28,39}

=> 14 + 28 > 39, 14 + 39 > 28, 28 + 39 > 14 (correct)

{4,16,19}

=> 4 + 16 > 19, 4 + 19 > 16, 16 + 19 > 4 (correct)

{4,11,13}

=> 4 + 11 > 13, 4 + 13 > 11, 11 + 13, > 4 (correct)

{5,16,21}

5 + 16 not > 21 (wrong)

63 is 75% of what number? Enter your answer in the box.

Viefleur [7K]

75% of x = 63

75/100 * x = 63 

So dividing by 75 / 100 on both sides 

x = 63 / 75 / 100 

x = 63*100/75 
x = 84 
The number is 84 

So 75% of 84 = 63! 

Hope that helps!
