Answer:
∠ A = 72°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ ECD = 180° - (90 + 54)° = 180° - 144° = 36°
∠ ACB = ∠ ECD = 36° ( vertical angles )
Since AC and BC are congruent then Δ ABC is isosceles, thus the base angles are congruent, that is
∠ A = ∠ B
∠ A = 
= 
= 72°
First of all, you have to define the value which cannot be changed, in this case it is $250, becuase it is a fixed fee.Then subtract 250 the fee from the amout of money that school can spend = 335
Then divide remaining cash by 8 the price per student : 335:8
and you will get 41.875
As you can see, you have to round the number down to 41, otherwise we would go over the school budget.
Therefore, the number of students is 41.
The least common multiple of 25 and 15 is 75. You'd do _ x 25 = 75 and _ x 15 = 75. The answer would be 3 and 5, so 5 packs of coins and 3 packs of coin holders.
