A cross section is the intersection of a solid an a plane
Answer:
x ≈ 6
Step-by-step explanation:
The legs of an isosceles triangle are congruent , both 2x - 4 , then
x + 2x - 4 + 2x - 4 = 24 , that is
5x - 8 = 24 ( add 8 to both sides )
5x = 32 ( divide both sides by 5 )
x = 6.4 ≈ 6 ( to the nearest whole number )
Answer:
a) well we know the hypotenuse and we know that all sides are 90 degrees, and that its an even square, so if we split it into a triangle , we know that the other 2 angles are 45 degrees total, with this we can calculate the other 2 sides, which round to 10 inches.
b) if we know the sides of the first side, knowing the fact that its a square we know that all sides are even, therefore, all sides are 10 inches, the formula the finding the perimeter is basic:
P=L(2) + W(2)
L being length, W being width and P being perimeter
so we add up all 4 sides, here is the equation:
10 + 10 + 10 + 10 = 10 x 4 = 40
With this, we know that the perimeter is 40 inches total
c) knowing how long the sides are, we can figure out the area through another basic formula:
A=L X W
With A meaning Area
since its a square, we know all the sides are even, so the width and length are both 10...
10 X 10 = 100

I Hope I Helped!
The answer to this question is area=length*width
