    ক)
    10 miles
    খ)
    20 miles
    গ)
    24 miles
    ঘ)
    30 miles

    Explanation

    By law of Right angle triangle, we can find oiut the distance of AC and CE. Thus, the entire distance from A to E. Now, AC = √(AB2 + CB2) = √(82 + 62) = √(64 + 36) = √(100) = 10 Again, CE = √(CD2 + DE2) = √(162 + 122) = √( 256+ 144) = √(400) = 20 Thus, AE = AC+ CE = 10 + 20 = 30 miles
