Question

Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x?
x+49−28=180
​x−49−28=180 ​
x + 49 + 28 = 180​ ​
x + 28 = 180

Answer 1

Step-by-step explanation:

1. x+49-28=180

x+49=180+28

x+49=208

x=208-49

x=159

2. x-49-28=180

x-49=180+28

x-49=208

x=208+49

x=257

3. x+49+28=108

x+49=108-28

x+49=80

x=80-49

x=31

4. x+28=180

x=180-28

x=80
