Justify each step of the solution by stating the property that was used to get to each step. Given: 2(10 − 13x) + 9x = −34x + 60 Step 1: 20 − 26x + 9x = −34x + 60 Step 2: −17x = −34x + 40 Step 3: 17x = 40 Step 4: x = 40 17

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
