which set of side lengths cannot form a right triangle?

Question

a. 16 mm, 30 mm, 34 mm b. 9mm, 15 mm, 17 mm, c. 8mm, 15 mm, 17 mm d. 9mm, 15 mm, 17mm

Answer 1

a^2+b^=C^2

9^2=81 15^2=225 81+225=306 17^2=289

306=289 FALSE

Neither B or D are right triangles

Answer 2

Answer is b) or d)

(Is it possible you accidentally repeated choice d from b?)

Right triangle sides must conform to the Pythagorean Theorem, i.e. A^2+B^2=C^2, where C is the hypotenuse, which of course must be the longest leg. Incidentally, the units of measure do not matter.

(a) 16^2+30^2=1156=34^2 works
(b) 9^2+15^2=306 ^=17^2, so does not work.
(c) 8^2+15^2=289=17^2 works.
(d) 9^2+15^2=306 ^=17^2, so does not work.

Answer 3

b. and d. cannot form a right triangle....

9^2 + 15^2 should equal 17^2 according to the Pythagorean theorem. 81 + 225 = 306

306/17=18

Answer 4

a and c follow the Pythagorean triple of 8:15:17.
b and d don't follow any Pythagorean triple and thus cannot form a right triangle.

Answer 5

9-15-17 can't be the sides of a right triangle.

so the answer should be b or d.

Answer 6

B) and D) are the same exact measurements. They cannot form a right triangle.

Answer 7

b and d look the same and cannot form a right triangle.

Answer 8

goodness! asking ppl to do your homework huh. tssk tssk tssk.

just use a^2 + b^2 = c^2.
for some reason both your b and d are the same thing...

Answer 9

sorry, answer withdrawn! (I misread what was being asked)
