The figure below is a square. Find the length of side x in simplest radical form with a rational denominator.
Mashcka [7]

Answer:

\frac{\sqrt{10}}{2}

Step-by-step explanation:

The diagonal forms two 45-45-90 triangles, with the diagonal being the hypotenuse of both. The Pythagorean Theorem states that a^2+b^2=c^2, where c is the hypotenuse of the triangle, and a and b are the two legs of the triangle.

From the Isosceles Base Theorem, the two legs of a 45-45-90 triangle are always equal. Since we're given a diagonal of \sqrt{5}, we have:

x^2+x^2=\sqrt{5}^2,\\2x^2=5,\\x^2=\frac{5}{2},\\x=\sqrt{\frac{5}{2}}=\frac{\sqrt{5}}{\sqrt{2}}=\frac{\sqrt{5}}{\sqrt{2}}\cdot \frac{\sqrt{2}}{\sqrt{2}}=\boxed{\frac{\sqrt{10}}{2}}

Ahmed wants to buy one of two skateboards. One skateboard costs $1 more than the
Papessa [141]

Answer:

1 skateboard will cost $73 and the other will cost $72

Step-by-step explanation:

Skateboard A (Original) = X

Skateboard B (+$1) = X + 1

Solving for X

(x + 1) + x = 145

2x + 1 - 1 = 145 - 1

2x = 144

2/2 = x  

144/2 = 72

x = 72
