Question

Which equation represents the relationship between the angles in this figure?

A. 148 + b = 90
B. 148 + b = 180
C. 2b + 148 = 90
D. 2b + 148 = 180

Answer 1

Answer:

Step-by-step explanation:

sum of angles on a straight line = 180

b + b + 148 = 180

2b + 148 = 180

Answer 2

Answer:

2b+148 = 180

Step-by-step explanation:

The three angles form a straight line so they add to 180

b+148+b = 180

Combine like terms

2b+148 = 180
