The perimeter of right isosceles ΔABC with midsegment DE is 16 + 8√2.
If right isosceles ΔABC has hypotenuse length h, then the two other sides are congruent.
side a = side b
Using Pythagorean theorem, c^2 = a^2 + b^2
h^2 = a^2 + b^2 a = b
h^2 = 2a^2
a = h/√2
If DE is a midsegment not parallel to the hypotenuse, then it is a segment that connects the midpoints of one side of a triangle and the hypotenuse. See photo for reference.
ΔABC and ΔADE are similar triangles.
a : b : h = a/2 : 4 : h/2
If a/2 = a/2, then b/2 = 4.
b/2 = 4
b = 8
If a = b, then a = 8.
If a = h/√2, then
8 = h/√2
h = 8√2
Solving for the perimeter,
P = a + b + h
P = 8 + 8 + 8√2
P = 16 + 8√2
P = 27.3137085

Answer:
40.374 ft
Step-by-step explanation:
We assume that the height of the goal on the football field is <em>h </em>(ft)
As it can be seen, the height of the goal is equal to the total of the man's height and the length of AB.
=> h = 5.5 + AB
The triangle ABC in the figure is the right angled triangle with Angle B = 90 degree and BC = 10 ft
In a right triangle, we have the equation as following:
+) tan of an acute angle = length of opposite side/ length of the adjacent side
We have: Angle C = 74 is an acute angle, its opposite side is AB, adjacent side is BC
=> tan Angle C = AB/ BC
=> tan 74° = AB/ 10
=> AB = 10. tan 74° = 34.874 ft
=> h = 5.5 + AB =5.5 + 34.874 = 40.374 ft
