C it’s 366 cm that’s how you would know the rectangular board
Answer: Sin N = 
Step-by-step explanation:
Since we have given that
In triangle MPN, ∠P=90°

As we know the formula for "Trigonometric Ratios":

By Pythagorus theorem , we get

So, we get,

Hence, Sin N = 
7x / 8 = 21
7x = 8*21
x = 24
None. The both have the same value. the fact that 2 zeroes was added to the end of 35.0500 doesn't make it bigger or smaller than 35.05
