A triangle with sides 3, 5, and 9 is a right triangle.

A triangle with sides 2 ft, 1.5 ft, and 2.5 ft. is a right triangle.

If a right triangle has legs with length 12 and 5, find the hypotenuse. Type in your numerical answer only; do not type any words or letters with your answer.

If a right triangle has legs with length 12 in. and 16 in., find the hypotenuse.

If a right triangle has legs with length 68 and 51, find the hypotenuse. Type in your numerical answer only.

steps

Step-by-step explanation:

A triangle with sides 3, 5, and 9 is "NOT" a right triangle, because 3 + 5 < 9

A triangle with sides 2 ft, 1.5 ft, and 2.5 ft. "IS" a right triangle 2²+1.5²=2.5²

If a right triangle has legs with length 12 and 5, find the hypotenuse. 13

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
