Nikita calculated the volume of the right triangular prism. Her work is shown below.

A triangular prism. The triangular base has a base of 8 centimeters and a height of 13 centimeters. The height of the prism is 7 centimeters.

Nikita’s Work:

Area of base = B = one-half b h = one-half (7) (8) = 28 centimeters squared.

Volume = B h = (28) (13) = 364 centimeters cubed.

Where, if any, did Nikita first make a mistake in her work?
Nikita used the wrong formula for the area of the base.
Nikita used the wrong measurements when finding the area of the base.
Nikita used the wrong formula for the volume of the prism.
Nikita did not make a mistake.

step-by-step explanation:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

the k side

step-by-step explanation:

plese mark mde brainliest!

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.
