Answer:
Angle C = 142 degrees
Step-by-step explanation:
A+B = 90
B+C = 180
Rearrange first equation to get B = 90-A
Plug this into the second equation:
90-A + C = 180
C = A + 90
Plug in A, C = 52 + 90 = 142
Answer
A. O.8743874374387438743....
Step by step explanation
Let's take a = O.8743874374387438743....
10a = 8.743874374387438743....
Similiarly,
10000a = 8743.874374387438743....
Since four decimal places are repeating.
Now subtract a from 10000a
10000 a - a = 8743.874374387438743.... - O.8743874374387438743....
9999 a = 8743
a = 8743/9999
8743/9999 = O.8743874374387438743....
That's it.
Hope you will understand the concept.
Thank you.

Answer:
a) E = 6500 -50d
b) 5000 kWh
c) the excess will last only 130 days, not enough for 5 months
Step-by-step explanation:
<u>Given</u>:
starting excess (E): 6500 kWh
usage: 50 kWh/day (d)
<u>Find</u>:
a) E(d)
b) E(30)
c) E(150)
<u>Solution</u>:
a) The exces is linearly decreasing with the number of days, so we have ...
E(d) = 6500 -50d
__
b) After 30 days, the excess remaining is ...
E(30) = 6500 -50(30) = 5000 . . . . kWh after 30 days
__
c) After 150 days, the excess remaining would be ...
E(150) = 6500 -50(150) = 6500 -7500 = -1000 . . . . 150 days is beyond the capacity of the system
The supply is not enough to last for 5 months.
