I'm sorry I can't answer this but the triangle looks like it's wearing a thong
A line of symmetry basically is like a reflection of a shape, so your answer is D.
At approximately 4.5 hours.
15.75x + 70 = 13.25x + 81
15.75x - 13.25x = 81 - 70
2.5x = 11
x = 4.4
found to the nearest tenth 4.5
The correct answer is 12
12 x 600 = 7200
