The answer is A, 75 degrees
add all like terms
2x+196
all triangles equal 180 degrees
2x+196=180
subtract the 196 from 180
2x= -16
divide
x= -8
plug into angle A
-8+83
A=75
Answer:The cost of one month of game-play =$20
Step-by-step explanation:
Let the cost of one month of gameplay be x
Then cost of game-play bought by Angie =3x.....(1)
and Then cost of game-play bought by Kenny=4x......(2)
Cost of each software package =$50......(3)
The the total cost =240= sum of costs of software bought by both of them and game-play)=50+50+3x+4x
⇒240=100+7x.......→(by adding like terms)
⇒140=7x⇒x=20.....→( dividing both sides by 7 )
∴the cost of one month of game-play =$20

The answer should be A, if he marked it up 70% just multiply 66 by 1.7 for your answer.
Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is 
= 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.
