Alexxandr [17]
Let, the number be "a"

\frac{a}{3} - 4=20

\frac{a-12}{3} =20

a-12 =20*3

a-12=60

a = 60 + 12

John is standing in his backyard and decides to estimate the height of a tree. He stands so that the tip of his shadow coincides
Andrew [12]

The tree is 820 inches tall using the similarity of triangles.

To get the height of the tree, we will use the properties of similar triangles expressed as:

\frac{70in}{7ft} = \frac{h}{75ft+7ft}\\\frac{70in}{7ft} = \frac{h}{82ft}\\

  • Note that 1 foot = 12inches
  • 7ft = 84in and 82ft = 984in

  • h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

\frac{70}{84} = \frac{h}{984}\\84h =70 \times 984\\84h = 68,880\\h=\frac{68,880}{84}\\h= 820in

Hence the tree is 820 inches tall using the similarity of triangles.
