Hello there! I can help you with this! So, let’s combine like terms to make a formula. Let’s do this: 7x + 19 = 180. You do this, because you are combining like terms and a straight angle which is seen is equivalent to 180 degrees. First, subtract 19 from both sides to get 7x = 161. Now, divide by 7 to isolate the x. 161/7 is 23. To check and see if this works, substitute x for the number. 23 * 6 = 138. 138 + 19 = 157. There. x = 23 degrees. Here are the measurements for both angles.
x = 23
Angle (6x + 19) = 157 degrees
Angle x = 23 degrees
