Answer:

68 is what I'm getting for x

70 is the correct length of DH

Explanation:

You can set up the proportion for this question.

99.2 / 62 = 112/(x + 2) Cross multiply

99.2 ( x + 2) = 62 * 112 Combine the right side

99.2(x + 2) = 6944 Use the distributive principle to remove the brackets.

99.2*x + 2*99.2 = 6944 Combine the factors on the left

99.2x + 198.4 = 6944 Subtract 198.4 from both sides

99.2x = 6944 - 198.4 Combine the terms on the right

99.2x = 6745.6 Divide both sides by 99.2

x = 6745.6/99.2

x = 68

DH = 70
