The length of a shadow of a tree is 150 feet when the angle of elevation of the sun is 39°. Approximate the height of the tree. (Round your answer to one decimal place.)

The height of tree is approximately 121.5 feet.

Step-by-step explanation:

We are given following in question:

Length of shadow = 150 feet

Angle of elevation of the sun =

The tree and the shadow forms a right angled triangle.

Thus, with the help of trigonometric relation, we can write:

Let x feet be the height of tree.

Putting all the values, we get,

Thus, the height of tree is approximately 121.5 feet.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
