A triangular piece of commercial real estate is priced at $4.75 per square foot. Determine the cost of the triangular piece of land if two sides of the lot measure 130 feet by 180 feet and the angle between these two sides is 50°

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
