Step-by-step explanation:
x + 29 + 12 = 89
x + 41 = 89
x = 48 for <CED
Answer:
60 seconds
Step-by-step explanation:
Hi!
After she goes forward 5 feet (4 seconds), and the backwards 3 feet (another 4 seconds), the total distance forward she travelled is 2 feet. Then, she moved forward 2 feet in 8 seconds.
Then, as this is repeated, she moves forward 2 feet every 8 seconds. After 7 repetitions she travelled 14 feet, and 56 seconds elapsed. Then she goes forward 5 feet in 4 seconds, and she finaly reaches the end of the hallway
(14 +5 > 15)
So, in 60 seconds she reached the end of the hallway.
The correct answer is 3.
The formula for the law of sines is the following:
P/sin P = Q/sin Q = R/sin R
So, if you break these up into two different equations, you will have:
P/sin P = Q/sin Q and P/sin P = R/sin R
To solve, get P alone on one side of the equation by multiplying the other side by sin P:
P = Q sin P/sin Q and P = R sin P/sin R
When you look at the answers, you'll see that the second equation is an option.
The thrid decimal place = 5 so you add 1 to the second place
answer is 4.44
