First, we subtract 20% of the amount from x, so the initial cost of the furniture should be 80% of x or 0.80x. Then, due to the sales taxs, this amount should be added with 6.25% of itself. Such that,
A = 0.80x + 0.0625(0.80x)
= 0.85x
They arent congruent when you look at the side lengths and area
Answer:
3h+18°+15h= 180°(straight angle)
=>18h+18= 180°
=>18h= 180-18° = 162°
=>h= 162°/18= 9
