A triangle has 3 different angle. Angle 1 is 87 degrees, angle 2 is 32 degrees. What is angle 3?
In a triangle, all 3 angles will add up to 180 degrees. To solve for the unknown angle, we would take 180 - angle 1 - angle 2. 180 - 87 - 32 = 61 Angle 3 = 61 degrees

How do you add this fraction together: 1/2 + 1/4
To add fractions, first change the denominator to be the same for both. In this case, the 1/2 is easier to change. We want the 2 on the bottom to become a 4, so we multiply the top and bottom by 1, represented in a fraction, in order for the 2 to be a 4. Multiplying 2 X 2 will make it 4. So to multiple the fraction correctly, we will multiple it by 2/2. 1/2 X 2/2 = 2/4 Now we can add them! 2/4 + 1/4 = 3/4
What does a 2/4 time signature mean?
Both numbers have a different meaning. The one on top stands for how many beats in a measure, in this case 2. The one on the bottom stands for which note gets one beat, the 4 means a quarter note gets one beat. If a 2 was on the bottom, then a half note would get one beat.
