Zarrin [17]

Answer:

10+2x

Step-by-step explanation:

A rectangle has 4 sides. Two pairs of sides are congruent.

For example a rectangle could have sides of 6, 10, 6, and 10.

So the perimeter would be the sum of those sides, 6+6+10+10.

6+6+10+10 can be written like 2(6)+2(10)

For the rectangle in your question it would be 5+5+x+x, which can be written like 2(5)+2(x)

Simplify to 10+2x.

OLEGan [10]

Answer:

5.77\ \text{m}

11.54\ \text{m}

Step-by-step explanation:

p = Height of pole

h = Length of role

b = Distance between the bottom of the rope and bottom of the pole = 10 m

\theta = Angle between the rope and the ground = 30^{\circ}

\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}

The length of the rope is 5.77\ \text{m}

\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}

The length of the pole is 11.54\ \text{m}
