Answer:

d=13.8

Step-by-step explanation:

secant-secant theorem: (a+b)b=(c+d)d

(14+20)14=(16+d)16

34*14=256+16d

476=256+16d

220=16d

d=13.75

Answer:

[tex]\frac{14}{16}=\frac{20}{d}[/tex]

[tex]14d=16\cdot \:20[/tex]

Multiply 16 × 20

[tex]14=320[/tex]

Now, Divide both sides by 14

[tex]\frac{14d}{14}=\frac{320}{14}[/tex]

[tex]d=22.9[/tex]
