Which of the following sets of numbers is not a Pythagorean triplet? 12, 16, 20 14, 48, 50 16, 30, 34 20, 48, 56

1 answer:

8 0

If a^2 + b^2 not equal c^2 then that set is not a Pythagorean

answer is 20, 48, 56

because

20^2 + 48^2 = 400 + 2304 = 2704
56^2 = 3136

2704 < 3136

What's the area of the triangle with 9mm 76mm 100mm

svlad2 [7]

9514 1404 393

Answer:

342 mm²

Step-by-step explanation:

The triangle shown has a base of 9 mm and a height of 76 mm. Its area is ...

A = 1/2bh

A = (1/2)(9 mm)(76 mm) = 342 mm²

The triangle shown has an area of 342 mm².

_____

Additional comment

The other leg of the right triangle with one leg 76 mm and hypotenuse 100 mm will be about 65 mm. The base shown is 9 mm, so any triangle with the dimensions shown will be a fairly skinny obtuse triangle, not the acute triangle in the picture. (This makes us suspect an error: the 9 mm dimension maybe should be 90 mm.)
