    Answer:

    Step-by-step explanation:

    To find B, C and D

    we make use of Pythagoras theorem

    since the line A= 8.5inch and looking at critically we can see the 3 inch meet it at the center (we divide 8.5 inch into 2 to give 4.25inch)

    using Pythagoras theorem

    hypothenus²= opposite²+adjacent²

    4.25²= 3²+b²

    18.0625 – 9 =b²

    9.0625 = b²

    b = √9.0625 = 3.0103986447≈3.01

    for c

    3² + 3.01² = C²

    9 + 9.0601 = 18.0601 =C²

    C = √18.0601 = 4.24971763768 ≈ 4.25

    C is a portion of the longest side meaning it will need to be divided by 2 = 4.25/2 =2.125

    to get D

    2.125² = 1.5² + D²

    4.25 = 2.25 +D²

    4.25 -2.25 = D²

    2 =D²

    D= √2 = 1.41421356237 ≈1.41
