Atriangle has two sides that measure 23 ft and 30 ft. which could be the measure of the third side?
a. 5 ft
b. 7 ft
c. 10 ft
d. 53 ft user: which of the following sets of numbers could be the lengths of the sides of a triangle?
a. 8 m, 8 m, 17 m
b. 8 m, 4 m, 2 m
c. 8 m, 16 m, 24 m
d. 8 m, 6 m, 4 m

For number one, the answer is 7 since 23 + 30 would equal 53 and adding the seven would make 60. Sixty is the ideal number for a triangle as it needs a 180 degree angle in it.

For number two, the answer is D, definitely D. The two smaller numbers added together should be larger than the third number, and 6 + 4 is bigger than 8 so this triangle is possible.
