Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

Answer: Bob can make it to base camp in about 1.6 hours.
If I am understanding the problem correct, Bob must drive 10 km to get to the road through the desert. Then, 45 km on the road. And finally, another 10 km off the road to get to the base camp.
We end to find the time for each section of the trip.
Start with the formula: d = rt or t = d/r
Now, we can divide to determine the amount of time for each section.
1) 10 / 30 = 0.333 hours
2) 45/50 = 0.9 hours
3) 10/30 = 0.333 hours
Add up all the times, and you get about 1.6 hours.
