Step-by-step explanation:
= 20
isolate the variable, by multiplying both sides by 5

the 5 cancels out on the right, leaving:

Answer:
Option C and D
Step-by-step explanation:
2π/3 refers 120°which falls in the second quadrant. In second quadrant sin value is positive and tan & cos value is negative.
tan 120 = - tan 60 = -√3
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°
