Let
point A----------------- > Bob
point B----------------- > lamppost that is to Bob left
point C----------------- > lamppost that is to Bob right
we know that
dAB=25 ft
dAC=30 ft
dBC=20 ft
see the attached figure
we use the law of cosines------------- > dBC²=dAB² +dAC² -2(dAB)(dAC)cos(alfa)
we have that
20²=25² +30² -2(25)(30)cos(alfa)-------- > cos (alfa)=(20²-(25² +30²))/(-2*25*30)
cos (alfa)=(400-(625 +900))/(-1500)= (400-(625 +900))/(-1500)=1125/1500=0.75
<span>alfa=arccos (0.75)= 41.4096 -------- > 41 °-------- > </span>∡ BAC
the answer is 41 °
<h2>The bond will be worth in total after 10 years is =$1,950</h2>
Step-by-step explanation:
Given,
Nora invested $1,500 in at a bond simple interest rate of 3%
here P= $1500 R= 3% and t = 10year
Simple interest(I) =
=$
=$ 450
<h3>The bond will be worth in total after 10 years is = $1,500+ $450</h3><h3> =$1,950</h3>
