It’s the one that says +3
That is not true. To find the midpoint of a line, you must add the values of x’s together and divide by 2 and then add the values of y together and divide by 2. The formula is (x1+x2/2 , y1+y2/2)
You first need to find the last angle measurement which is
60 because 60+15+105= 180
Sin60 Sin105
——— = ———— Cross multiply
a 2
Sin60 * 2 = Sin105*a
1.7 = Sin105*a Divide both sides by sin105
1.79 = a
1.8 ≈ a
There are 3 feet in a yard. 27 feet ÷ 3 = 9 yards. Now you have the number of yards. Divide this by 48. You will get 0.1875 yards per dress.
