Explanation:
The keyboard and screen can be thought of as flat rigid sheets of paper. They are joined along one single line which is where the hinge is located. Any two planes intersecting will form a single straight line assuming these planes are not parallel to one another.
Answer:
15 rooms
Step-by-step explanation:
1:$32 = x:$500
$32×x = 1×$500
x = $500/$32
x = 15, 625
Area 1st rectangle = 10 * 7 = 70 cm^2
length of 2nd rectangle is 2*7 = 14 cm
Area 2nd = 10 * 14 = 140 cm^2
140/70 = 2
The 2nd triangle was twice as big as the 1st. Answer A
C. because u can't name a congruent triangle by angle angle angle
Refer to the attached image.
Given the rectangle ABCD of length 'l' and height 'h'.
Therefore, CD=AB = 'l' and BC = AD = 'h'
We have to determine the area of triangle AEF.
Area of triangle AEF = Area of rectangle ABCD - Area of triangle ADF - Area of triangle ECF - Area of triangle ABE
Area of triangle ADF = 
= 
= 

Area of triangle ECF = 
= 
= 

Area of triangle ABE = 
= 
= 

Now, area of triangle AEF =
Area of rectangle ABCD - Area of triangle ADF - Area of triangle ECF - Area of triangle ABE
= 
= 
=
=

= 27 units
Therefore, the area of triangle AEF is 27 units.
