Answer:
Area of trapezoid = 67.6 square units
Step-by-step explanation:
Area of a trapezoid is given by the expression,
Area of the trapezoid =
Here, and
are the parallel sides of the given trapezoid.
And '' = Height between the parallel sides
From the given triangle ABE,
m(∠ABE) = m(∠ABC) - m(∠EBC)
m(∠ABE) = 120° - 90°
= 30°
By applying cosine rule in the given triangle,
cos(30°) =
BE = units
By applying sine rule in ΔABE,
sin(30°) =
AE = 3 units
Length of
Length of [AE = FD, since given trapezoid ABCD is an isosceles trapezoid]
Height between the parallel sides
Area of the trapezoid =
=
=
= 67.6 square units
Answer:
C. a reflection in the y-axis
Step-by-step explanation:
The mapping statement for the transformation of the vertices of the triangle ABC is given as following:
A(0,2)→A'(0,2)
B(2,9)→B'(-2,9)
C(4,2)→C'(-4,2)
To find the correct transformation for the given statement.
Solution:
From the given statements, the general transformation statement for the the vertices of the triangle can be given as:
The above transformation shows a reflection in the y-axis as the transformation in y-axis changes the sign of the x-coordinate of the point.
