143.7 I believe since you take 6.80*20=136+46=2.3*20
136+46=182
182*7.65%=168.08
168.08*8.95%=153.04
153.04*6.1%=143.7

Answer:
<h3>
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78</h3>
Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78
I think x=9 so 29 plus 7 is 36. I think it is a 36 degree angle. Correct me if im wrong
