Mean simply means average
so just add them all up and divide by 5
22 + 37 + 49 + 15 + 71 = 195
195/5 = 39
mean = 39
Answer:
$3
Step-by-step explanation:
Here, 3x-70 = x [ corresponding angles ]
3x-x = 70
2x = 70
x = 35
So, ABC = 3x-70 = 3(35)-70 = 105-70 = 35 degrees
So, your final answer is 35
Answer:
Step-by-step explanation:
Use law of cosines
c² = a² + b² - 2abcosθ
cosθ = (c² - a² - b²) / -2ab
c = length of AC = √(8 - 5)² + (4 - (-5))² = √90
b = length of AB = √(8 - 6)² + (4 - 3)² = √5
a = length of BC = √(6 - 5)² + (3 - (-5))² = √65
cosθ = (√90² - √65² - √5²) / -2√65√5
cosθ = 20 / -36.05551...
cosθ = - 0.5547001
θ = 123.69°
A = 7
B = 14
For A:
(7(sqrt)2)sin(45) = 7
7/sin(30) = 14
