Step-by-step explanation:

One way of approaching this would be to separate 48:

48 times 6 is equivalent to (40 + 8) times 6, or 240 + 48, or 288.

That's just one of many examples.

48 times 6 could also be expressed as 48 times (2 + 4) = 96 + 192 = 288.

And so on.

Next time please share more of the instructions.  Thank you.

NemiM [27]

Answer:

Measure of angle 3: C (46 degrees)

Step-by-step explanation:

As there is no attachment, I will assume the question is in reference to a triangle. Knowing that a triangle contains 3 angles the answer can be retrieved through simple steps:

m∠1 + m∠2 + m∠3 = 180 degrees, by Sum of Angles in Triangle Theorem, <em>thus;</em>

Through substitution + algebra:

134 + m∠3 = 180,

m∠3 = 46 degrees
