Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
3 1/2=7/2 1 1/3=4/3. 7/2=2×3=6=7×3=21.3×2=6=4×2=8
21-8=13=13/6 or 2 1/6
Maybe try to add the 90s or multiply i depends
Answer:B
Step-by-step explanation:
The original price would be $189.20 because the decimal is 0.14 is ( you move the decimal point to the right of where the number starts) then multiply that decimal to 220 and it would be 30.8. Subtract 30.8 and you get $189.20
