You need to break it down to the common multiples. For 27 it’s 9,3. 9 can also be divided by 3. Now you are left with the number 3
73.25 is mean median is 38 mode is 3
The two angles with x in them are the same. Set them equal to each other and solve for x:
4x-5 = 3x + 11
Add 5 to both sides:
4x = 3x +16
Subtract 3x from both sides:
x = 16
Now solve for the angle next to y:
4x - 5 = 4(16) -5 = 64 -5 = 59
Y + 59 make a straight line and equals 180, so subtract 59 from 180 to get y:
y = 180 - 59 = 121
Answers:
X = 16, y = 121
28x+20y =14*4 = 56
28x + 21y = 9*7 =56
=> y=0, x = 2
