The hypotenuse of right triangles ABC and DEF are both segments of the same line. The right triangles are similar, with leg AB corresponding to leg DE, and leg BC corresponding to leg EF. If AB=24,BC=6, DE=-x, and EF =y-7, what is the equation of the line. Use the proportion 6/24=y-7/-x to find your answer.

step-by-step explanation:

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.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
