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 °--------

the answer
is 41 °
When -29/8 is written as a decimal it becomes
Which is equivalent to -3.63, rounded to the nearest hundredth.
Now from here we will be able to tell if they're < , > or =
So, -3.63 is > -3.62
ANSWER: -29/8 > -3.62
There are 88 green marbles!
g=numGreenMarbles
b=numBlueMarbles
g+b=104
g=5b+8
b=104-g
g=5(104-g)+8=520-5g+8
g=88
Answer:
5
Step-by-step explanation
2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65
what do i mean?
2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people
