Step-by-step explanation:
<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:

Solving for X

Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m
Answer:
This is very cute.
Step-by-step explanation:
G= 40
5x8=40
40/8=5
All you have to do is inverse operations so instead of dividing you multiply your 5 and 8 to get 40 and then check your work.
The answer is B. In this case when you isolate the variable it just takes 2 steps. The others require more steps and tedious calculation.
Answer:
68
Step-by-step explanation:
4 + (11 - 3)^2
= 4 + 8^2
= 4 + 64
= 68
