sin(angle)=opposite leg/hypotenuse
sin(20) = 10/ hypotenuse
hypotenuse = 10/sin(20) = 29.238 ( round off as necessary)
Answer:
29.24 centimeters
Step-by-step explanation:
The trigonometry of angles states that in a right angled triangle with sides a, b, c representing the opposite, adjacent and hypotenuse sides respectively, and an angle A° opposite the side a
Then,
Sin A° = a/c
Cos A° = b/c
Tan A° = a/b
Hence,
Sin 20° = 10/c
c = 10/Sin 20°
c = 29.24 centimeters
