Step-by-step explanation:
Angles in a quadrilateral add to 360 degrees. So, x = 360-88-142-106=24 degrees

2x -1 is the answer I believe
Answer:
x=59/5 or x=11.8 depends on which one you want to do both are true
Step-by-step explanation:
Start with what you are given
angle 4= 5x+6 and angle 3=65 because lines m and n are both parallel angle4=angle3 in other words 5x+6=65
what you want to do is get x by itself.
1. Subtract 6 from both sides
5x+6-6=65-6
5x=59
2. Divide both sides by 5
5x/5=59/5
x=59/5
3. Check to see if you can simplify the fraction and if you teacher wants it in decimals or exact fraction.
x=59/5 or x=11.8 they are the same just ones a decimal the other is left as a fraction
0.05, 0.5, 5/8
5/8 is greater than 0.5 since 0.5 = 1/2 which equals 4/8
