Answer:
106
Step-by-step explanation:
If you find the sum of the interior angles, you can determine the supplement to z.
Then all you have to do to get z is to subtract it from 180.
Method
The supplement of 72 is 180 - 72 = 108
The supplement of 51 is 180 - 51 = 129
The supplement of 60 is 180 - 60 = 120
The supplement of 71 is 180 - 71 = 109
Let y = the supplement of z
y + 108 + 129 + 120 + 109 = 540
y + 466 = 540
y = 540 - 466
y = 74
z + y = 180
z + 74 = 180
z = 180 - 74
z = 106
I hope that get's rid of your headache.
Answer:
Hope this much helps you.
I beleive the system of equations would be:
a+b=4000
0.1a+0.04b=352
I cant say for sure because the question did not list the cost of a and b together but rather the number of both items together
Answer:
7 cm
Step-by-step explanation:
base area = (base length x base height)/2 = (2x6)/2 = 6 cm^2
height = V / base area = 42 / 6 = 7 cm
