Answer:

The answer to your question is: x = 45°

Step-by-step explanation:

We must know that the sum of the internal angles in a triangles equals 180°.

Then                ∠A + ∠B + ∠C = 180°

Substitution

                       55° + 80° + ∠C = 180°

                       135° + ∠C = 180°                        Simplification

                       ∠C = 180 - 135

                       ∠C = 45°

                       ∠C = x

                      x = 45°                                       Result

A train leaves at 15.42 and arrives at its destination at 16.56.
Tasya [4]

Answer:

90/1.5=60 mph

Step-by-step explanation:

I assume that the train is traveling at constant speed.

Between 12:45 pm and 2:15 pm the train has traveled 180-90=90 miles. So 90 miles in 1.5 hours which means that its speed is 90/1.5=60 mph

Answer: 2 inches, 3 inches, or 3.125 and 2.083


Explanations:
The simplest way is to take 20% of the 2.5 inches and go that much above & below 2.5 inches.

2.5 x 20% = 2.5 x 0.20 = 0.5

So 2.5 - 0.5 = 2 inches was predicted
And 2.5 + 0.5 = 3 inches was predicted.

The more complicated way is to see number + 20% of that number = 2.5, and what number - 20% = 2.5.

Which solution sounds more like what you’re doing in class right now?

If it’s the more complicated way:

0.8x = 2.5 (80% of the predicted rain value equals 2.5)
x = 3.125 inches was predicted

1.2x = 2.5 (120% of the predicted rain value equals 2.5)
x = 2.083 inches was predicted

Sorry, this is probably confusing. Let me know what questions you have.
