The diagonal of a square is x units. What is the area of the square in terms of x? square units square units 2x square units squ
STatiana [176]

For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:

l ^ 2 + l ^ 2 = x ^ 2

Where:

l: It's the side of the square.

2l ^ 2 = x ^ 2\\l ^ 2 = \frac {x ^ 2} {2}

We know that the area of a square is given by:

A = l ^ 2

So, the area is:

A = \frac {x ^ 2} {2}

Answer:

A = \frac {x ^ 2} {2}

#6 help needed with math
yarga [219]

Answer: Secant of angle A = √2

Step-by-step explanation:

From the given right angle triangle,

AB represents the hypotenuse of the right angle triangle.

With m∠B as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine Cosine of m∠A, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos A = √5/√10

Secant = 1/Cosine

Therefore,

Secant of angle A = √10/√5 = √2
