Angles in a 4-sided shape = 360 degrees
2x + x + 101 + 85 = 360
3x + 186 = 360
3x = 174
x = 58 degrees

Answer:
25%
Step-by-step explanation:
The average cost of the automobile in 2013 is $16,000
The present cost now is $20,000
Therefore the rate of increase between the two automobiles can be calculated as follows
= 20,000-16,000/16,000
= 4,000/16,000
= 0.25×100
= 25%
Hence the rate of increase is 25%
