Mia’s clock radio communicates the time, plays the radio, and sounds the alarm at a set time, but mia has trouble seeing the numbers on the clock at night because they are not backlit. how well does the design meet the purpose for which it was designed?

Ithink its the same as usual

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"
