Answer:
1st solution is -2x+12
2nd solution is 5x+31

Step-by-step explanation:
x = 2(180 - x) - 12
3x = 348
x = 116
The measure of the angle is 116 degrees.
Answer: x=5, x=2

Based on Diego's normal usage of his phone, if the battery is at 75%, the phone will not last the whole trip.
<h3>How long will the phone battery last?</h3>
First find out how long each percentage of battery life lasts:
= 15 / 100
= 0.15 hours
If Diego is going on a 12 hour trip with 75%, the length of time it would last is:
= 0.15 x 75
= 11.25 hours
This is less than the 12 hours required so the phone will not last the whole trip.
Rest of question:
At 100%, the battery can go for 15 hours.
