X/80 = 70
x = 80x70
x = 5,600
Answer:
Therefore option A.) 0 is correct.
Step-by-step explanation:
The graph is attached.
The solution of the equations as seen from the intersection of the equations in the graph is (0,2).
Therefore x = 0 is the solution which gives y = 2 for both equations.
Therefore option A.) 0 is correct.
You have to find out what X is which you need to do -2 - (-11) and then do -9 - (-11) after that do you-2 x -2 and get -4
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
