The first letter can be any one of 8. For each of those . . .
The second letter can be any one of the remaining 7. For each of those . . .
The third letter can be any one of the remaining 6. For each of those . . .
The fourth letter can be any one of the remaining 5. For each of those . . .
The fifth letter can be any one of the remaining 4.
The total number of possibilities is (8 x 7 x 6 x 5 x 4) = <em>6,720</em> .
(That's 8! / 3! .)
Note:
If you're allowed to use the same letter more than once,
then there are 8 choices for each of the 5 letters.
The total number of possibilities then is (8 x 8 x 8 x 8 x 8) = 32,768 .
(That's 8⁵ or 2¹⁵ .)
Answer:
∠ 1 = 20°, ∠ 2 = 160°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, that is sum to 180°
x - 12 + 5x = 180 , that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = x - 12 = 32 - 12 = 20°
∠ 2 = 5x = 5 × 32 = 160°
