Answer:
The answer is
49.5°
Step-by-step explanation:
Let the angle be x
Since the triangle is a right angled triangle we can use trigonometric ratios to find the value of x
To find the value of x we use cosine
[tex] \cos( \theta) = \frac{adjacent}{hypotenuse} [/tex]
From the question
the adjacent is 13
the hypotenuse is 20
The angle is
[tex] \cos(x) = \frac{13}{20} \\ x = \cos^{ - 1} ( \frac{13}{20} ) \\ x = 49.4583[/tex]
We have the final answer as
49.5°
