Choice a
9. The Law of Sines says a:b:c and
are the same ratio.
The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL
choice b
10.
DEF and FEG are supplments, FEG=180-DEF=180-114=66
DEF and HEG are opposite angles, so congruent HEG=DEF=114

Answer:
Step-by-step explanation:
length times width = area
so you have 8.5w=93.5
divide 8.5 on both sides to get your answer
w= 11
so your width must be 11 inches
The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28
So, he must work 213.28 : 8.75 = 24.3748571429...
Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.
Recheck : 25 x 8.75 = 218.75 ( > 213.28)
Answer:
Step-by-step explanation:
7/9+1/6+3/5
Least common factor is 90
Multiply
70/90+15/90+54/90
Is 139/90 which is. 1 49/90
2x-6=2x+2
We move all terms to the left:
2x-6-(2x+2)=0
We get rid of parentheses
2x-2x-2-6=0
We add all the numbers together, and all the variables
-8!=0
