Trapezium ABCE is made from parallelogram ABCD
and isosceles triangle ADE.
A
B
106°
E
D
Work out the size of angle AED.
Answers
Answer:
Angle AED=32 degrees
Step-by-step explanation:
angle ADC=angle ABC because parallelogram
then angle ADC=106 degrees
angle EDA is supplementary to angle ADC (ADC+EDA=180 degrees)
then angle EDA=74 degrees
because triangle ADE is isosceles, angle EAD=angle EDA
since the total angles in a triangle =180 degrees,
Angle AED=180-2(74)=32 degrees
Applying the definition of isosceles triangle and parallelogram, the size of angle AED is: 32°.
Facts about Parallelogram and Isosceles TriangleThe opposite angles in a parallelogram have equal angle measures.The two angles that are directly opposite the two equal sides in an isosceles triangle are congruent.Thus:
m∠ABC = m∠ADC = 106° (opposite sides of parallelogram)
m∠ADC = 106°
m∠ADE = 180 - 106 = 74°
m∠AED = 180 - 2(74) (isosceles triangle)
m∠AED = 32°
Thus, applying the definition of isosceles triangle and parallelogram, the size of angle AED is: 32°.

Step-by-step explanation:
From the graph, the correct options are given as,
B. Mia left her house 10 minutes before Erick left his house.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graphs show their distances from home over the same 30-minute period as they walked to the park.
From the graph,
It can be concluded that,
Both reach the park at the same time, as the termination point of the curve is the same.
The graph of mia starts after 10 minutes Erick, which implies Mia left her house 10 minutes before Erick left his house. And Erick walked the same distances as Mia during the last 10 minutes as the slope of the last segment of both curves is the same.

What is the y=mx+b of the equation 3x−2y=12
Answers
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
Answer:
y=3/2x-6
Step-by-step explanation:
3x-2y=12
isolate the y:
-2y=-3x+12
get rid of the coefficient in front of y by dividing by -2
y=-3/-2x+12/-2
y=3/2x-6

x = 9
Step-by-step explanation:
Perimeter of rectangle = 2(l+b) = 42
=> 2(x+3 + x)
=> 2 (2x + 3) = 42
=> 4x + 6 = 42
=> 4x = 42 - 6
=> 4x = 36
=> x = 36/4
=> x = 9
Hope it helps :)
Answer:
Formula = (l + b) x 2= 42 so answer = x=9
Step-by-step explanation:
l =x
b =x+3
( x+x+3) * 2 =42
2x +3 x 2 = 42
2x +3 = 42/2
2x +3 = 21
2x = 21 - 3 =18
x = 18/2
x=9
