Answer:
Yes
Step-by-step explanation:
In order to make a triangle with non-zero area, the sum of the shorter two sides must be greater than the longest side.
Here, 4 + 4 > 7, so the lengths can form a triangle.
See the attached figure to better understand the problem
we know that
AM=MD
so
triangle AMD is an isosceles right triangle
therefore
its height is half its width.
Then
AB = (1/2)AD----------Equation 1
Perimeter=2*[AB+AD]=34 in ---------> AB+AD=17-------> Equation 2
I substitute 1 in 2
(1/2)AD +AD = 17
(3/2)AD=17
AD=17*2/3----------> AD=34/3-------> 11 1/3 in
AB=(1/2)AD--------> AB=(1/2)*34/3--------> AB=17/3-------> AB=5 2/3 in
the answers are
AD=11 1/3 inAB = 5 2/3 in

1.25 hours = 75 miles = 1/4 of 60 is 15 (of the 1.25)
75/15 (miles per gallon)
Answer:
0.0707 radians
Step-by-step explanation:
Given that:
The dimension of the rectangular box is:
length (l) = 20 inches
width (w) = 20 inches
height (h) = 2 inches
The length of the diagonal of the rectangular box is :
The length of the diagonal of the base of the rectangular box is:
If we take a critical look at a rectangular box; we will realize that the diagonal of the base is the adjacent side & diagonal of the box is the hypotenuse of a triangle formed by the rectangular box.
Therefore, the angle between them is :
to radians
