Trigonometric Ratios
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:
[tex]\displaystyle \tan 33^\circ=\frac{X}{30.5}[/tex]
Solving for X
[tex]X=30.5\cdot \tan 33^\circ[/tex]
Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m

what is 2 8/15+ 1 1/30
Answers
Answer:
3 17/30
Step-by-step explanation:
In order to do this problem, we have to get the two fractions to have the same denominator
So we change 2 8/15 into 2 16/30 (multiplying both the numerator by 2, if you don't know why this works then ask me) and then we just add. So 2 16/30 + 1 1/30 = 3 17/30

A pair of fire towers uses technology to search for forest fires. Let the center of the forest be the origin on a coordinate grid. The first fire tower is located 5 km east and 8 km south of the center, and the second fire tower is located 7 km west and 4 km north of the center. The technology at the first tower can locate fires within a radius of 10 km and the second tower within a radius of 9 km. The system of inequalities represents this scenario.
