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.

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
