[tex]\(\theta\)[/tex] is an angle in a right-angled triangle.

[tex]\[ \tan \theta = 24 \][/tex]

What is the value of [tex]\(\theta\)[/tex]?

Give your answer in degrees to 1 decimal place.



Answer :

To find the value of [tex]\(\theta\)[/tex] given that [tex]\(\tan \theta = 24\)[/tex], we need to follow these steps:

1. Understand the Relationship:
The tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side. Here, [tex]\(\tan \theta = 24\)[/tex].

2. Calculate the Angle in Radians:
To determine the angle [tex]\(\theta\)[/tex], we use the inverse tangent function ([tex]\(\arctan\)[/tex] or [tex]\(\tan^{-1}\)[/tex]). This function will provide the angle in radians. Let’s denote [tex]\(\theta\)[/tex] in radians as [tex]\(\theta_{\text{radians}}\)[/tex].

[tex]\[ \theta_{\text{radians}} = \arctan(24) \][/tex]

3. Convert Radians to Degrees:
Angles in trigonometry are often more readable in degrees. To convert the radians to degrees, we use the fact that:

[tex]\[ 1 \text{ radian} = \frac{180}{\pi} \text{ degrees} \][/tex]

Thus, the angle in degrees is given by:

[tex]\[ \theta_{\text{degrees}} = \theta_{\text{radians}} \times \frac{180}{\pi} \][/tex]

4. Performing the Calculation:
From the calculation steps, we know:

[tex]\[ \theta_{\text{radians}} \approx 1.5291537476963082 \][/tex]

Converting this to degrees:

[tex]\[ \theta_{\text{degrees}} \approx 87.61405596961119 \][/tex]

5. Round to One Decimal Place:
Finally, we round the angle to one decimal place:

[tex]\[ \theta_{\text{degrees}} \approx 87.6 \][/tex]

Therefore, the value of [tex]\(\theta\)[/tex] in degrees, rounded to one decimal place, is:

[tex]\[ \theta \approx 87.6^\circ \][/tex]
