The side lengths of different triangles are given. which triangle is a right triangle? a. 6,7,13 b. 21−−√,99−−√,11 c. 10,60,61 d. 35−−√,14−−√,7

D

Step-by-step explanation:

By definition for a right triangle with sides a, b, c, where c is the hypotenuse,

the following must be true:

a² + b² = c²

By using this formula on all the choices, we find that only D satisfies this formula

i.e.

for

a = √35 > a² = 35

b = √14 >b² = 14

c = 7 > c² = 49

a² + b² = 35 + 14 = 49 which is equal to the value of c² above

the answer is y = 11.54

hope this : )
