Answer:

Step-by-step explanation:

∠ FHI and ∠ JHI form a straight angle and are supplementary, thus

3x + x = 180, that is

4x = 180 ( divide both sides by 4 )

x = 45

Thus

∠ FHI = 3x = 3 × 45 = 135° → C

Write 2,670,000 in scientific notation.

hjlf

Scientific notation is just rewritten so that it has a single digit in front of the decimal and that this is multiplied by a power of ten that makes this decimal equal to the original number.

In this case we have 2.67 million. Well a million is equal to 10^6, because 10*10*10*10*10*10=one million.

So in scientific notation you would write:

2.67X10^6
