Answer:
angle j = 90
angle k = 29
angle L = 61
Step-by-step explanation:
180 = 90 + (4x-19) + (5x+1)
90 = 9x - 18
108 = 9x
x = 12
Answer:
Due to having 24 divisors.
Step-by-step explanation:
360 has many factors which might be the reason it was chosen for the number of degrees in a full turn. There are total 24 divisors of 360 number which make it the highest factors among all numbers. All circles are divided into 360 even parts so that the Sun would move through 1 part each day. Each of these parts was describes 1 degree and this division give us the idea that a circle contains 360 degrees so we can say that this is the reason that 360 is chosen in degrees.
(4x - 1)(3x + 5)
Try different combinations of the front number's factors with combinations of the last number's factors. The FOIL until you find one that works.
FIND THE AVERAGE
WHICH IS 6.11 OR 6
FIND THE DISTANCE OF EACH VALUE FROM 6:
17, 23, 8, 20, AND 12
ADD ALL OF THOSE NUMBERS AND DIVIDE BY 6
MEAN DEVIATION = 13.33 OR 13 3/9
