<u>Trigonometric Formulas</u>
To solve this problem, we must recall some basic relations and concepts.
The main trigonometric identity relates the sine to the cosine:
The tangent can be found by
The cosine and the secant are related by
They both have the same sign.
The sine is positive in the first and second quadrants, the cosine is positive in the first and fourth quadrants.
The sine is negative in the third and fourth quadrants, the cosine is negative in the second and third quadrants.
We are given
Find the cosine by solving
We have placed the negative sign because we know the secant ('sex') is negative and they both have the same sign.
Now compute the tangent
Rationalizing
Answer:
The answer to your question is the letter D) 46°
Step-by-step explanation:
Data
length = 25 ft
Opposite side = 18 ft
Angle = Ф
To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.
Sin Ф = Opposite side / hypotenuse
-Substitution
sin Ф = 18/25
-Simplification
sin Ф = 0.72
-Result
sin⁻¹ Ф = 0.72 = 46°
Given
26% = several simulations of a football player playing two games
Find the percentage of the simulations in each of the two games
2x = .26
2x = .26
---- -----
2 2
x = .13 * 100
x= 13
The answer is 13% of simulations would the football player be most likely to get a touchdown in each of the two games.
