Can a triangle with the given side lengths 4in,6 in, 8in and 18cm,24 cm and 30cm be a right triangle

99

step-by-step explanation:

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

answer4 to the second power is 16

and 4 to the third power is 64,

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
