Answer:
x = 24.10 to 2 decimal places.
Step-by-step explanation:
The picture contains a right angled triangle(a triangle that has one of its angles to be 90 degrees).
Since all sides are not given, the Pythagoras theorem cannot be used. Instead, we will use
We will use trigonometric ratios.
Sin # = opposite/ hypotenuse.
Cos # = adjacent / hypotenuse.
Tan # = opposite / adjacent.
From the triangle, we have the following information :
Adjacent side = 20
Hypotenuse = x
# = 34 degrees.
So we will use
Cos # = adjacent / hypotenuse.
Cos 34 = 20/x
xcos 34 = 20
x = 20/cos 34 = 20/0.83
= 24.09639
Approximately 24.10 to 2 decimal places.
