Q 2. Part 2 - Find the error(s) and solve the problem correctly. Find sin 520 Answer: sin 52 = -0.9866 B i U Font Family 3. Part 3 - Discussion Question Name 4 other angles whose cosine is the same as cos 2. Explain using mathematical language how you know this is true. (Calculations only using a calculator is not considered mathematical language). Is this statement true or false? Explain your answer. All angles that have the same cosine will have the same sine.[ O 1.Part1- Application Heron's Area Formula Let a, b, and c be sides of AABC. Let s equal the \"semi-perimeter\" of A ABC' atb+ec 2 The areaof AABC'is A=4/s(sa)(sb)(sc) Your friend just bought a triangular plot of land to open a dog daycare center. The lengths of each side of the triangle plot of land is 225 ft, 900 ft, and 850 ft. The warehouse will need to be 11,000 square feet and have 10 parking spaces at 320 square feet each. Will this plot of land be big enough to house the warehouse and 10 parking spaces. Why or Why not? Be sure to show your mathematical equations as proof. Compare the area using Heron's with the area using the formula in lesson 2. Which formula was easier to use? Why? B /i U FontFamily ~AAr A O T = O L @ 0O s /@
