how do I do the first question and second
?


Answer for Problem 2:
x=61 degrees
Step-by-step explanation:
I'm not completely sure of problem 1, but I know what problem 2 is.
Tip: triangles always add up to 180 degrees.
1. 16+42= 58
2. 180-58= 122
3. 122 divided by 2= 61 degrees
ANSWER: x=61 degrees.
For the first one, the angles are vertical so they have the same measurement. Set them equal.
110 = 6x + 2; subtract 2 from both sides
108 = 6x; divide both sides by 6
18 = x
For the second one, there are a total of 180° in a triangle so set them equal to 180.
2x + 16 + 42 = 180
2x + 58 = 180; subtract 58 from both sides
2x = 122; divide both sides by 2
x = 61
I hope this helps!
