a living room floor consists of an area and hardwood. the area of the rug is 187 square feet. what is the area of the entire living room. (i'm attaching a picture for the rest of the problem) 40 points and brainliest if you answer correctly.

the solution is 12x-6y

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.

current in the circuit at time t is /, then the power delivered to the resistor is
