Option C: 180 
Explanation:
 Complementary angles add upto 90 degrees and supplementary angles add to 180 degrees
 Given A=40
 B = Complement of A =90-40 =50
 C = Supplement of B = 180-50 =130
 Therefore B+C = 50 +130 =180.

Charra [1.4K]

Answer:

True

Step-by-step explanation:

First statement

[a b c | d][x]

[a b c]x=d

ax+bx+cx=d

Second statement

Ax=d

Given that A = [a b c]

[a b c]x=d

ax+bx+cx=d

ax+bx+cx=d

Then, they are going to have the same solutions
