Answer:
∠ I = 39°, ∠ J = 51°, ∠ K = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 angles and equate to 180
3x + 21 + 5x + 21 + 90 = 180, that is
8x + 132 = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Then
∠ I = 3x + 21 = 3(6) + 21 = 18 + 21 = 39°
∠ J = 5x + 21 = 5(6) + 21 = 30 + 21 = 51°
∠ K = 90°

Answer:
1/3
Step-by-step explanation:
Alice can select any ball from her bag and it goes into Bob's bag. Then bob has 6 balls including two of one color.
Suppose they are {A,B,B,C,D,E}
Now Bob must draw one of the two balls of the same color (B) in order to have the same content of the two bags.
P(bags same content)= 2/6= 1/3
The probability that the bags content are the same= 1/3
Part a: Cost of downloading album B = 13.3 euros
Part b: Cost of downloading album B = 12.6 euros
Number of tracks in album A = 11 tracks
The total cost of downloading album A = 10.45 euro
Cost of each track on album A = Total cost of album/Number of tracks in the album
= 10.45/11
= 0.95 euro
Part a:
Number of tracks in album B = 14 tracks
Cost of album B = Number of tracks in album B * Cost of each track
= 0.95*14
= 13.3 euros
Part b:
The cost of 5 tracks on album B is 5p less therefore, the cost of 5 tracks will be 0.90*5 = 3.60 euros
The cost of 9 tracks on album B is 5p more therefore, the cost of 9 tracks will be = 1*9 = 9 euros
The total cost of downloading album B = 9+3.6 = 12.6 euros
