Given the figure above, if

Since 10 is 149 and it sits on a flat line, then there is the angle next to it (that being angle 9). All flat lines equal 180 degrees. so 180-149=31

since angle 9 is 31, and angle 9 is a corresponding angle to angle 3, angle 3 must be 31 degrees.

except a rational number. : )

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
