Ok, I'm not completely sure, I'm taking a bullet here. But lemme know what you get
Answer:
73
Step-by-step explanation:
Since DA is the diameter, this means that you can divide the circle into two half-circles. You will solve with the right half-circle. A half-circle has a 180 total degrees. Add up the values given and solve for x.
(2x) + (7x - 4) + (85) = 180
2x + 7x - 4 + 85 = 180
9x - 4 + 85 = 180
9x + 81 = 180
9x = 99
x = 11
Now that you have the value of x, solve for m∠CZB.
m∠CZB = 7x - 4
m∠CZB = 7(11) - 4
m∠CZB = 77 - 4
m∠CZB = 73
The last answer is correct
Well since each shelf holds 40 you would add up the two shelves to 80 then add 5 on one shelve to get 85. Since he has room for 40 you would subtract 5 and get 35
Answer:
9
Step-by-step explanation:
We know that a=1/5. Therefore, we can substitute 1/5 in for a into the expression.
10a + 7
10(1/5)+7 <em>Multiply 1/5 and 10</em>
2+7 <em>Add 2 and 7 </em>
