Answer:
20 m
Step-by-step explanation:
Here, we will take,
The distance from top of the building to the tip of the shadow = Hypotenuse = 37 m
The length of shadow of the building = base = 32 m
let, height of the building = perpendicular = p
According to the Pythagoras Theorem,
(Hypotenuse)² = (Base)² + (Perpendicular)²
<em>h</em><em>²</em><em> </em><em>=</em><em> </em><em>b²</em><em> </em><em>+</em><em> </em><em>p²</em>
<em>p²</em><em> </em><em>=</em><em> </em><em>h²</em><em> </em><em>-</em><em> </em><em>b</em><em>²</em>
<em>p²</em><em> </em><em>=</em><em> </em><em>37</em><em>²</em><em> </em><em>-</em><em> </em><em>32</em><em>²</em><em> </em>
<em>p²</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em><em>6</em><em>9</em><em> </em><em>-</em><em> </em><em>1</em><em>0</em><em>2</em><em>4</em>
<em>p²</em><em> </em><em>=</em><em> </em><em>34</em><em>5</em>
<em>p </em><em>=</em><em> </em><em>1</em><em>8</em><em>.</em><em>5</em><em>7</em>
and if we round the solution to nearest tenth it will be 20.
<u>Hence,</u><u> </u><u>height </u><u>of </u><u>the </u><u>building </u><u>is </u><u>2</u><u>0</u><u> </u><u>m.</u>

Answer:
x=1
Step-by-step explanation:
To solve, we need to get x by itself. To do this, preform the opposite of what is being done to the equation, and everything that is done to one side, must be done to the other.
5(2x-8)+15= -15
First, subtract 15 from both sides, since 15 is being added
5(2x-8)+15-15=-15-15
5(2x-8)=-30
Next, divide both sides by 5 since 5 is being multiplied
5(2x-8)/5= -30/5
2x-8= -6
Add 8 to both sides, since 8 is being subtracted
2x-8+8= -6+8
2x= 2
Divide both sides by 2, since 2 is being multiplied
2x/2= 2/2
x=1
Take Lucy's cars (8) and multiply them by Tim's cars (t) to get the expression 8*t.
