Answer: AB=√17, AD=√98,6

Step-by-step explanation:

AB²=BC²+AC²-2*BC*AC*cosACB

AB²=5²+4²-2*5*4*0,6=25+16-24=17

AB=√17

AD²=AC²+CD²-2*AC*CD*cosACD

cosACD=cos(180°-ACB)=-cosACB

AD²=4²+7²-2*4*7*(-0,6)=16+49+33,6=98,6

AD=√98,6

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than

Fofino [41]

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: $x+2x+x-6=458$

$4x-6=458$

$4x=464$

$x=116$

So on the third day, Aiden read $x-6=116-6=110$ pages.
