What is the value of x?<br> Enter your answer in the box
Marina CMI [18]

Answer:

x = 45º

Step-by-step explanation:

well since a triangle has to equal 180º

then we just have to subtract 88º and 55º from 180º

180 - 80 - 55 = 45

therefore, x = 45

From 2:45 P.M. to 4:20 P.M. how many hours and how many mins?
Liula [17]
To find out the time in between a different time you can add in segments, you can add 15min to 2:45, to make it 3:00, then add 60 more minutes to make it 4:00, so now we have 75 min, then add 20 minutes to get the time to 4:20 pm, you then add up all the segments, which equal 95 minutes. In hours it would be 1 hour, and 35 minutes. Hope you understand that, of not, tell me, and ill fix it and make it more understandable.
