Question

in the figure below, b is between a and c, and c is between b and d. if bd = 11, ac = 9, and bc = 4, find ad. a b c d ad =

Explanation:

Step1: Find AB

$AB = AC - BC = 9 - 4 = 5$

Step2: Find CD

$CD = BD - BC = 11 - 4 = 7$

Step3: Calculate AD

$AD = AB + BC + CD = 5 + 4 + 7 = 16$

Answer:

16
