Answer:

the length of one leg of the triangle is, 7 units

Step-by-step explanation:

Definition: 45°-45°-90°

In a 45°-45°-90°  triangle, the length of one leg of the triangle is \frac{1}{\sqrt{2}} times the length of Hypotenuse of the triangle.

Let x be the length of one leg of the triangle.

As per the statement:

The hypotenuse of a 45°-45°-90° triangle measures 7√2 units

⇒\text{Length of Hypotenuse side} = 7\sqrt{2} units.

By definition of 45°-45°-90° ;

x =\frac{1}{\sqrt{2}} \cdot \text{Length of hypotenuse side}

Substitute the given values we have;

x = \frac{7\sqrt{2}}{\sqrt{2}}

Simplify:

x = 7 units

Therefore, the length of one leg of the triangle is, 7 units

A circular pool with a diameter of 18 ft will have a uniform 4 ft concrete walkway poured around it. If the concrete cost $4.25
zysi [14]

A circular pool with a diameter of 18 ft will have a uniform 4 ft concrete walkway poured around it. If the concrete cost $4.25 a square foot, how much will it cost for the concrete?

This can be solve be solving the area of walkway

Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2

= 276.46 sq ft

Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
