Answer:
1) 140 2)68 3) 125 4) 140
Step-by-step explanation:
for these, because you're trying to find the angle from 180 degrees, you would subtract the angle on the 180 degree line from 180.
1) 180-40 = 140
2) 180-112 = 68
3) 180-55 = 125
4) 180-40 = 140
Hope this helps!
For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
Answer:
If it cost Hudson $28.20 to send 188 text messages, it would cost $9.45 to send 65 text messages. So the answer would be $9.45.
Step-by-step explanation:
Let me explain why. The answer is 9.45 because, 28.20 divided by 188 is 0.15. Then, if you multiply 0.15 by 63 you get 9.45.
28.20/188=.15
.15x63=9.45
So yeah, that's why if it cost Hudson $28.20 for 188 messages, it would be $9.45 to send 65 messages. So again, the answer is 9.45. I hope this was helpful and makes you understand it more now. :D
Answer:
4 and 10 - acute
2 is acute, but 3 is obtuse
8 and 12 - acute
6 and 12 - acute
1 is obtuse 2 is acute
15 and 11 are obtuse
9 is obtuse but 8 is acute
2 and 4 are acute.
Step-by-step explanation:
I believe this is correct.
A right angle is a perfect corner. Think of a square and look at the corner, it doesn't go farther or shorter when it hits a side if you know what I mean by that. An acute angle is shorter than a right angle, or stops before it can be called a right angle. An obtuse angle is bigger than a right angle, or ends after the right angle point. I hope what I have just said here helps you with future problems!! Good luck :))
