Answer:
100°
Step-by-step explanation:
The angle between chords is the average of the intersected arc angles.
∠FKJ = ½ (84° + 76°)
∠FKJ = 80°
∠HKJ is supplementary to ∠FKJ.
∠HKJ = 180° − 80°
∠HKJ = 100°
Since 25% is smack in the middle between 20% and 30%, it will take equal volumes of ech to make a 25% solution.
Since 4 gallons of 30% solution was used, so 4 gallons of 20% solution will be needed.
Answer: player A = 11/16 and player B = 5/16
Step-by-step explanation:
If a coin was to be tossed to determine the winner possible outcomes using arithmetical triangle.
Player A needs 2 points = 11
Player B needs 3 points = 5
Total outcome of tossing a coin = 16
Player A = 11/16 = 0.6875
Player B = 5/16 = 0. 3125
Or
Using the fifth roll of the pascal triangle (2+3) outcome
( 1, 4, 6, 4, 1 )
Addition of the first 3 represent Player A chances of winning = ( 1+ 4 + 6 ) = 11
And the last two = ( 1 + 4 ) = 5 represents the chances of team B winning
Total number of outcome = ( 1 + 4 + 6 + 4 + 1 ) = 16
