Answer:
u = 150
Step-by-step explanation:
Number of vertices:
10
Find the sum of the interior angles:
180(n - 2)
180(10 - 2)
180(8)
1440
To find u:
u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)
u = 1440 - (1290)
u = 150
Answer:
The answer is 4th point
Step-by-step explanation:
√5(10 - 4√2)
= (√5×10)-(√5×4√2)
= 10√5 - 4√10
Answer:
Heating and cooling costs might vary considerably.
4(2) - 5 = 3
4(5) - 5 = 15
4(8) - 5 = 27
4(9) - 5 = 31
so the answers are 3, 15, 27, and 31
