13.60 because you add the coupon discount back on and subtract tax cost and divide by 2
Step-by-step explanation:
180 - 34 = 146
one angle is a right angle, angle across it is 146, 360 - 90 - 146 = 124
divide that by two to get the measures of the remaining two angles (62 degrees)
180 - 62 = x
118 = x
The expression is consistent witch means and can keep going a long time the answer is x0x0
