Answer:

A; 140 degrees

B; 40 degrees

C; 140 degrees

Step-by-step explanation:

B. is the same as the given angle.

A and C are also the same angles.

We can either do the 360* or the 180* way.

I'll do them both.

180=40+A

subtract 40 from both sides.

140

A. and C are represented by 2x.

360=(40+40)+x

360=80+2x

280=2x

140

In both ways used, the answer is that A and C equal 140 and B equals 40

Answer:

A = 140°

B = 40°

C = 140°

Step-by-step explanation:

1. Since we know that opposite angles are equal, b = 40°

2. Since we also know that the angle of a line adds to 180°,

a = 180° - 40°

So, 140°

Then repeat step 1 to find C through A.

Multiply everything in the second parenthesis by x.

-3x^3 + 3x^2 + x

Multiply everything in the second parenthesis by 2.

-6x^2 + 6x + 2

Combine these two equations together.

-3x^3 + 3x^2 + x - 6x^2 + 6x + 2

Combine like terms.

-3x^3 - 3x^2 + 7x + 2

Hope this helps!

Suppose Austin, Texas, is hit by a tornado that destroys 25 percent of the housing in the area. Would you expect the total expen

notsponge [240]

Answer:

greater than what it was before

Step-by-step explanation:

Remember, a tornado usually causes significant structural damages to houses within its area of impact., and this requires running expenses to repair the damage.

Hence, since the term expenditure, also implies expenses; we can expect the total expenditure on housing after the tornado to be greater than what it was before the tornado since families would be paying for repairs.
