Austin estimates that the distance from his house to his work is 13.5 mi. The actual distance is 14.5 mi. To the nearest tenth of a percent, what is the percent error in Austin's estimate?
A: 6.9% B: 1% C: 0.68%

the answer to the question is a  

it has the same slope and the same y-intercept.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
