Nadya [2.5K]

Answer:

The length of the pipe = 17 feet

Step-by-step explanation:

length = 15 feet

width = 8 feet

Pythagorean theorem,

(diagonal)² = (length)² +(width)²            {all angles of rectangle are 90°}

                   = 15² + 8²

                   = 225 + 64  = 289

diagonal    = √289 = √ 17 * 17

                   = 17 feet

Dahasolnce [82]

Answer:

3\sqrt{17}$ or \approx 12.37$ Units

Step-by-step explanation:

In the attached diagram

CA=CO+OA

CO=DB

Therefore:

5=2+OA

OA=3 Units

The angle between a tangent line and a radius is 90 degrees. therefore triangle OAB is a right triangle with:

OB=12 units

OA=3 units

Using Pythagoras theorem

AB=\sqrt{3^2+12^2}\\ =\sqrt{153}\\=3\sqrt{17}$ or \approx 12.37$ Units
