Answer:
∠ B = 45°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent , then
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Then
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°
It is -3 because it had a negative slope

It’s because the answer is 8y
Answer:
Left side simplifies to (-2/3)^1 and the right side simplifies to (-2/3)^(-n) which means 1 = -n so n = -1.
Answer:
7. 21 times more
8 1/9
Step-by-step explanation:
7. 2 pants, 5 tops , 3 gloves, 7 masks
2*5*3*7 =210 outfits
10 * what = 210
10 *21 = 210
21 times more
8. There are 36 possible outcomes
11 121 131 14 15 16
21 22 23 24 25 26
31 31 33 34 35 <em>36
</em>
41 42 43 44 <em>45</em> 46
51 52 53 <em>54</em> 55 56
61 62 <em>63</em> 64 65 66
There are 36 possibilities and 4 have a sum of 9
P (sum of 9) = outcomes with sum of 9/total
4/36 = 1/9
