Factor each expression. Problem: r^2 +12r +27 Answer: (r + 3) (r + 9)

1 answer:

3 0

Think of it like this, what two numbers when multiplied together, you get 27, and when they add together, you get 12? The answer is 9 and 3,
Your answer here would be (r+9)(r+3) when factored.

<u>Trigonometric Ratios </u>

The ratios between the sides of a right triangle are called trigonometric ratios.

If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.

The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.

This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.

The trigonometric ratio that relates both legs is the tangent:

$\displaystyle \tan 33^\circ=\frac{X}{30.5}$

Solving for X

$X=30.5\cdot \tan 33^\circ$

Using a calculator:

X = 19.81 m

The height of the tree is 19.81 m
