Answer:
x = -7, A = 65 degrees
Step-by-step explanation:
[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]
Therefore,
x + 72 + x + 51 + 71 = 180
2x + 194 = 180 [collect like terms]
2x = -14 [subtract 194 from both sides]
x = -7 [divide both sides by 2]
To find A, we substitute the value of x into x + 72:
A = (-7) + 72
A = 65 degrees.
Hope this helps! :D
Answer:
5+7*x
Step by step explanation.....
Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.
Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500
If t=time, then for this question, we just need to plug in 2 seconds :

The height is
