What is the solution to this equation? 6+7(b−1)=5+b

A)b = 0
B)b = 1
C)b = 2
D)b = 5

b is equal to 1

Step-by-step explanation:

I guessed and it came to be the right answer.

6+7b-7 = 5+b.

6+6b-7 = 5

6+6b=12

6b = 6

B= 1

1 so it’s B

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
