I haven't done proofs in a while, but one thing that might help is that only if two lines were parallel would angles 3 and 1 be congruent (3 is congruent to 2, which is congruent to 1, so they're all congruent to each other).

A box contains 35 gems, of which 10 are real diamonds and 25 are fake diamonds. Gems are randomly taken out of the box, one at a

Answer:

Step-by-step explanation:

The total number of ways of selecting 3 gems of any kind without replacement is 35 * 34 * 33 = 39270

Now selecting 2 gems from 25 is 25C2

25 C 2 = 25 * 24/2 = 300

Selecting one good gem is 10

Total selection = 300 * 10 = 3000

P(gems) = 3000 / 39270

P(gems) = 300/3927

P(gems) = 100/1309

Marissa subtracted a negative number from a positive number. Her result was negative. Is that reasonable? Explain.

No. If you subtract a negative from a positive number its equivalent to adding the inverse of that negative number. If you add a negative to a positive number It is equivalent to subtracting from that positive number.
