Answer 1

B = 155

C = 25

D = 155

Explanation:

Keep in mind the principles of vertical angles and total degrees.

We know that C = A because they're vertical angles, so A = C = 25 degrees.

We know that B = D because they're vertical angles. The sum of all the angles will be 360 degrees, because it's a full rotation, so

A + C + B + D = 360

Plug in B for D, because they're equal.

25 + 25 + B + B = 360

50 + 2B = 360

2B = 360 - 50

2B = 310

B = 310/2 =

B = D = 155 degrees

Answer 2

C= 25

B and D= 65

Explanation:

The whole thing equals 180, and if one side (A) is 25 then the other side (C) is 25 too. 180-50= 130. 130/2 is 65 and that's B and D.
