Answer:
m∠CFD is 70°
Step-by-step explanation:
In the rhombus
- Diagonals bisect the vertex angles
- Every two adjacent angles are supplementary (their sum 180°)
Let us solve the question
∵ CDEF is a rhombus
∵ ∠E and ∠F are adjacent angles
→ By using the second property above
∴ ∠E and ∠F are supplementary
∵ The sum of the measures of the supplementary angles is 180°
∴ m∠E + m∠F = 180°
∵ m∠E = 40°
∴ 40° + m∠F = 180°
→ Subtract 40 from both sides
∵ 40 - 40 + m∠F = 180 - 40
∴ m∠F = 140°
∵ FD is a diagonal of the rhombus
→ By using the first property above
∴ FD bisects ∠F
→ That means FD divides ∠F into 2 equal angles
∴ m∠CFD = m∠EFD = m∠F
∴ m∠CFD = (140°)
∴ m∠CFD = 70°
Answer: $ 55
Step-by-step explanation:
When interest is compounded continuously, the final amount will be
When interest is compounded daily, the final amount will be
, where P= Principal , r = rate of interest , t = time
For Hunter , P= $750, r =
t = 18 years
For London , P= $750, r =
t = 18 years
Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55
Hence, Hunter would have $ 55 more than London in his account .
