To prevent the spread of communism to the south Vietnam
By applying the sine trigonometry, the value of leg s is equal to: F. 8 units.
<h3>How to apply basic trigonometry?</h3>
In order to determine the value of leg s, we would apply basic trigonometry. From the diagram of the right-angled triangle shown above, we can deduce the following parameters:
Next, we would use the sine trigonometry to determine the value of leg s:
Sinθ = Opp/Hyp
Sin45 = s/8√2
1/√2 = s/8√2
s√2 = 8√2
s = (8√2)/√2
s = 8 units.
