How do i solve the science club went on a field trip. the numbers paid $60 for transportation plus $15 per ticket to the planetarium. the total for the trip was $120?

your answer is the frist one

hop i

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

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.
