Step-by-step explanation:

Find the distance of BC.

Tan(40)=55/BC

BC=65.55m

Find the distance of BD.

Tan(36)=55/BD

BD=75.70m

Use BC and BD to find CD

BD-BC=CD

75.70-65.55=CD

CD=10.15m

natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

Number of pages she read on Monday = $\frac{4}{8}$ x 252 = 126 pages
Number of pages she read on Tuesday = 28 pages
Number of pages she read on Wednesday = $\frac{1}{4}$ x 252 = 63 pages
