because one angle measures 98, and another angle measures more than 90 (obtuse angle), and that does not match with 180 degree as a sum of all angles' measures..
An obtuse angle means that the angle is larger than 90 degrees. Since the total interior angle measures in a triangle must add up to 180 degrees, you cannot have 2 angles more than 90 degrees. Hope this helps!
You would multiply 60 (that's the percentage off) by 320 ( the price of the T.V) and then subtract the answer you got from multiplying the two from the original price of the T.v (320)
