Hello from MrBillDoesMath!
Answer:
75
Discussion:
A plane triangle has 180 degrees. Using this in the diagram gives
x + 81 + angle BAC = 180 (***)
(The diagram is a bit fuzzy but I think the above numbers are accurate)
The diagram also shows that (156 + angle BAC )= 180 as a straight line has 180 degrees. So
angle BAC = 180 - 156 = 24
Substituting this in (***) above gives
x + 81 + 24 = 180 =>
x + 105 = 180 => (as 81 + 24 = 105)
x = 180 107 = 75
Check: Does
x + 81 + angle BAC = 180 ?
75 + 81 + 24 = 180. Yes
Thank you,
MrB

4x+16+5x+25=9x+41
Step-by-step explanation:
Hihi!
To answer the equation you'd take
W = - 0.414t + 129.549
64 = 129.549 -0,414t
0.414t = 129.549 - 64
0.414t = 65.549
t = 65.549/0.414
t = 158.33 minutes = 158 minutes + 20 seconds.
So the answer would be around 160 minutes!
I hope I helped!
