Asquare is cut in half on the diagonal, creating two equal triangles. each triangle has an area of 0.32 square units. what is the side length, in units, of the original square?

0.8

Step-by-step explanation:

Let's say s is the side length of the square.  When the square is cut diagonally, each triangle has a base of s and a height of s.

Area of a triangle is:

A = ½ bh

Given A = 0.32, b = s, and h = s:

0.32 = ½ (s)(s)

0.64 = s²

s = 0.8

The side length of the square is 0.8 units.

First we need to find out the area of the square. Since 1/2 of the square( the triangle) is .32 square units, multiply .32 by 2 to find the area.

.32*2=64

Now, find the square root of .64

The square root of .64 is .8.

The side length of the original square is .8 units.

Hope this helps!

thus, the first answer choice, y = sec x, is the correct one
