Answer: x = 16</h3>
============================================
Explanation:
On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.
From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x
We get the following:
(5x+12)+(6x-8) = 180
5x+12+6x-8 = 180
(5x+6x)+(12-8) = 180
11x+4 = 180
11x = 180-4
11x = 176
x = 176/11
x = 16
1. 6×(3+2)÷10 = 3
Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3
2. 12-(3×3)+11 = 14
Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14
3. (10×0.4) + (10×0.8) = 12
Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12
4.(8 ÷ 4)×(4-2) = 4
Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4
5.8.5-10÷2 = 3.5
Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5
6.18-(8÷2)+25 = 39
Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39
Answer:36pi or 113.0973355...
Step-by-step explanation:v=4/3pir^3 so 4/3pi*27 so 36pi or 113.0973355...
