Answer:
The first one towards the left, or the green triangle, would be 70 degrees.
The second one, or the one in the middle, would be 108 degrees.
The last one, or the yellow triangle, would be 65 degrees.
136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
