Hello I need help! IM GIVING BRAINLIEST, FIVE STARS AND THANKS to best answer :)
Natalka [10]

Answer:

1. 4 hours and 10 minutes

2. 8:40 to 12:00

4. 6 hours and 50 minutes

5. 2:25 pm

6. 9:15 am to 12:35pm

7. 3:00pm

(second) 7. 2 hours and 45 minutes

Step-by-step explanation:

1. 2+4 = 6 so then after add 10 to the 45

4 hours and 10 mins

-

2. 8+3= 11 so its 11:40 right now, add the other 20 minutes, you end up with 12:00.

-

4.It's better off to start with 12 so add 3 hours and 30 minutes to get to 12:00pm. Now to 3:20pm would obviously be 3 hours and 20 minutes.

3 hours + 3 hours = 6 hours. 30 minutes + 20 mins = 50 mins. 6 hours and 50 minutes.

-

5. 10:15 + 4 hours would be 2:15 now add the 10 and that would be 2:25pm.

-

6. 9:15 a.m to 12:35pm would be right. The elapsed time is 5 hours and 20 minutes. 10:30 P.M to 1:15 A.M would be close but it's 5 minutes lesser. 11:10 pm to 2:15 am would be 3 hours and 5 minutes. 6:45pm to 10:00pm would be 3 hours and 15 minutes.

-

7. Making it simpler, add 15 minutes so that makes it 12:00pm. Then just add the 3 hours. 3:00P.M.

3:00 pm is your answer.

-

(second) 7. 10:30 pm to 1:15am. Also making it simpler, add 1 hour and 30 minutes. Now just add 1 hour and 15 minutes. Add both times,

1 hour and 30 minutes + 1 hour and 15 minutes = 2 hours and 45 minutes.

Find the measure of the indicated angle. Need help please.<br> I need explanation
Zolol [24]

Answer:

BC =21.03540021

Step-by-step explanation:

We know the measure of angle B since the sum of the angles of a triangle add to 180

A + B+ C = 180

61+ B + 12 =180

B = 180 - 12 -61

B =107

Then we can use the law of sines to find BC

sin B           sin A

-------- = -------------

AC                BC

sin 107       sin 61

-------- = -------------

23                BC

Using cross products

BC  sin 107 = 23 sin 61

BC = 23 sin 61/ sin 107

BC =21.03540021
