Answer:
One side is 9 m
Step-by-step explanation:
Perimeter = 36 m
Perimeter = 4a
a = P/4
a = 36/4
a = 9
Refer to the diagram shown below.
Because ACFD is a parallelogram, its opposite angles are equal. Therefore
x = m∠ACF = m∠BCF = 48°
Similarly,
y = m∠CAD = m∠CFD
The sum of the angles inside a parallelogram is 360°. Therefore
48° + x + y + y = 360°
Because x = 48°,
48° + 48° + 2y = 360°
2y = 360° - 96° = 264°
y = 132°
Because ABED and FEBC are congruent, therefore
y = m∠DAB = m∠CFE = 132°
x = m∠ADE = m∠FCB = 48°
Because FEBC is a parallelogram, the opposite angles are equal. Therefore
m∠CBE = m∠CFE = y = 132°
m∠BCF = m∠BEF = x = 48°
Answer:
The measures of all angles of trapezoid FEBC are
m∠BCF = 48°
m∠BEF = 48°
m∠CBE = 132°
m∠CFE = 132°
So one trip = 4 km
two trips = 8
8 + 4 = 12
i believe your answer is 12
Thanks!
If AB is 128 centimeters long what is xe
B.) thousandths because the first one is tenths and the second is hundredths. Also because it is after the decimal
