The sum of the angles in any triangle is 180 degrees. If one of the three angles is 90 degrees (a right angle) the the sum of the other two angles is 90 degrees. Therefore each of the other two angles must be acute.
The statement is TRUE.
The contribution of overhead as percentage of sales will be found as follows:
Overheads=134000+13550+27800=$175350
Sales=$191000
thus the percentage of overheads will be:
overheads/sales
=175350/191000
=0.91806
=91.806%
