Use the law of cosines to find a:
So to use the given numbers you get:
Which would come out to equal about 35.94
so a=35.9
Answer: x= -2
Step-by-step explanation: use pemdas
10x + 8 = 3(x - 2) distribuite parenthesis
10x + 8 = 3x - 6
10x + 8 = 3x - 6 add like terms
7x +8= -6 add like terms
7x= -14 divide to get x alone
x= -2
Answer:
d = 1
Step-by-step explanation:
5(d+2)=15 (Given)
5d + 10 = 15 (distribute)
5d = 5 (subtraction)
d = 1 (division)
Answer:
x = 30
y = 15
Step-by-step explanation:
<u><em>All the angles are </em></u><u><em>90°</em></u><u><em>, so set 6y and 3x equal to 90, like so:</em></u>
6y = 90
<u><em>Divide both sides by 6:</em></u>
y = 15
<u>Solving for x:</u>
3x = 90
<em><u>Divide both sides by 3:</u></em>
x = 30
1. Make a frequency distribution table. Draw a histogram. Age frequency. 2 4 6 8 10 12 14 16... make a tally in the appropriate class. 5... frequency is 50, which is the number of entries in sample data set.
