Answer:
Step-by-step explanation:
Remark
If the figures are similar then this is a proportion question. A proportion is 2 equation ratios. The ratios can have at most 1 unknown.
Givens
DC = 7
ML = 4.9
AB = 4
JK = x
Equation
DC/ML = AB/x Substitute values into equation and solve
Solution
7/4.9 = 4/x Cross Multiply
7x = 4 * 4.9 Combine the right.
7x = 19.6 Divide by 7
7x/7 = 19.6/7
x = 2.8
Answer
x = <u>2.8</u>
