Find the length of the hypotenuse of a right triangle with legs of 5 and 13. round to the nearest tenth, if necessary.
13.9
12
169
25

13^2 + 5*2 = 169 + 25 = 194
hypotenuse  =  square root (194) = 13.9

answer A. 13.9 (first choice)

A^2+b^2=c^2
5^2+13^2=c^2
25+169=194
Square root of 194 is 13.9
the answer is A. 13.9
hope this helps

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
