Answer:
C
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )
x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )
x =
=
=
×
= 4

Each day 1 traditional candle (shamash) is lit along with a number of candles representing that day of Chanukah. I'm taking it that a new Shamash candle must be used each day.
Total Candles = 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 44
Givens
Formula
Sum = (a + L)*n/2
Solution
- Sum = (2 + 9)*8/2
- Sum = (11)*4
- Sum = 44
If this is wrong can you tell me what assumption I'm making that is incorrect.
