Answer:
[tex]\ta \theta =38.7^{0}[/tex] is the approximate value of angle Ф.
Step-by-step calculation:
To determine:
We have to determine the angle Ф.
Fetching Information and solution steps:
As two sides are given:
- Opposite side of angle Ф = 4 units
- Adjacent side of angle Ф = 5 units
The missing angle can be calculated by the formula
[tex]\tan \theta ={\frac {opposite }{adjacent}[/tex]
So,
[tex]\tan \theta ={\frac {4 }{5}[/tex]
[tex]\ta \theta =tan^{-1}( {\frac {4 }{5})[/tex]
[tex]\ta \theta =38.7^{0}[/tex]
So, [tex]\ta \theta =38.7^{0}[/tex] is the approximate value of angle Ф.
