Answer:
<h2>The line that forms the shadow is 10.26 meters long, approximately.</h2>
Step-by-step explanation:
This problem is about a right triangle, becasue the truck and its shadow are perpendicular.
We are gonna call the distance of the shadow on the ground, as the image attached shows.
To find the answer, we need to use Pythagorean's Theorem, where the hypothenuse is 11.2 meters, and one leg is 4.5 meters.
Therefore, the line that forms the shadow is 10.26 meters long, approximately.
-1 since E’s reflection over y=x is b so if b has x cord -1 the y cord of e is -1
The perimeter of a polygon is the sum of the lengths of all its sides. A rectangle has 4 sides, and opposite sides are congruent, so 2 sides have length x + 5, and 2 sides have length 11. Add all the lengths and set the sum equal to 50. Then solve the equation for x.
x + 5 + x + 5 + 11 + 11 = 50
2x + 32 = 50
2x = 18
x = 9
Answer: x = 9
