A triangle is 180°, so the 3 angles should add up to 180°.

To find m∠R, you can do this:

m∠S + m∠R + m∠T = 180°

56° + m∠R + 30° = 180°

m∠R + 86° = 180° Subtract 56 and 30 on both sides

m∠R = 94°

The answers are 3/8 and 1/6.

There are 8 possible outcomes in the sample space for flipping 3 coins. Of those, 3 include two heads and 1 tail. This makes the probability 3/8.

Choosing a quarter for the first coin is 3/10, since there are 3 quarters out of 10 coins. After this, choosing a dime is given by 5/9, since there are 5 dimes out of 9 coins left:
3/10(5/9) = 15/90 = 1/6

Answer:

n = -1

Step-by-step explanation:

-8n + 4 (1 + 5n) = -6n - 14

-8n + 4 + 20n = -6n - 14 Distribute

12n + 4 = -6n - 14 Combine Like Terms

18n + 4 = -14 Add 6 on Both Sides

18n = -18 Subtract 4 on Both Sides
