Yesterday, Gary sold 9 pairs of shoes and 3 pairs of boots for $1260. 
Today, he sold 4 pairs of shoes and 10 pairs of boots for $2120. 
How much does Gary charge for each type of footwear?

1) Identify the angle and label the sides (hyp, opp, adj)
2) The sides will determine which ratio you are to use. In this case, 8 is the opp and 15 is the adjacent, so the ratio you use is tangent (tan).
3) Change the ratio 8/15 to a decimal by dividing them (8/15 = 0.5333)
4) Look in the Trig Table under the tan column to find the value closest to 0.5333 to find the corresponding angle (which is 28 degrees)]]> 2017-02-24 20:28:26 UTC https://padlet.com/thach_thao_phan/mpm2d_week4/wish/156140965 thach_thao_phan https://padlet.com/thach_thao_phan/mpm2d_week4/wish/156312408 https://student.desmos.com/?prepopulateCode=7ucae
