Divide 171 by 3. 57 Therefore the middle integer is 57 <span>Therefore the highest integer is "2" higher = 59 </span> <span>The lowest integer is 2 lower to "balance" the higher digit = 55 </span>
<span>Therefore using common sense rather than "let x=....." the answer is 55, 57 and 59.</span>
The horizontal distance is given by the formula: tan θ=opposite/adjacent where: θ=21 opposite=2000 ft adjacent=a thus calculating for a we get: tan 21=2000/a thus a=2000/tan 21 a=5210.18 ft
graph of a linear equation is a line, two linear equations has no solution mean two lines has no intersect/common point, those two lines must be parallel
