Answer:
∠CDF = 54
Step-by-step explanation:
In ΔAEB,
AE ≅ AB
∠ABE = ∠E = x {Angles opposite to equal sides are equal}
∠EAB + ∠E +∠ABE = 180 {angle sum property of triangle}
26 + x + x = 180
26 + 2x = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
∠ABE = ∠E = 77
In quadrilateral AECF
∠A + ∠E + ∠C + ∠F = 360
90 + 77 + ∠C + 90 = 360
∠C + 257 = 360
∠C = 360 - 257
∠C = 103
∠FCD + ∠BCD = ∠C
∠FCD + 67 = 103
∠FCD = 103 - 67
∠FCD = 36
ΔFCD,
∠FCD + ∠CDF + ∠CFD = 180
36 + ∠CDF + 90 = 180
∠CDF + 126 = 180
∠CDF = 180 - 126
∠CDF = 54
Answer:
the first number equals 6
the second number equals 10
Step-by-step explanation:
3×n1 + 5×n2 = 68
3×n2 - 4×n1 = 6
3×6 + 5×10= 68
\/ \/
18 + 50= 68
3×10 - 4×6 = 6
\/ \/
30 - 24 = 6

Answer:
(38/29) +(8/29)i
Step-by-step explanation:
_____
Multiply numerator and denominator by the conjugate of the denominator to make the denominator a real number.
Actual selling price: $7.35
Markdown: $2.65
10-2.65= 7.35
