Using the sine ratio, Sin R = √2/3 = 0.47.
<h3>What is the Sine Ratio?</h3>
The sine ratio is given as, sin ∅ = length of the opposite side of the right triangle to the reference triangle / the length of the hypotenuse of the right triangle.
Given the following:
Reference angle (∅) = angle R
Length of opposite side = √2
Length of hypotenuse = RT = ?
Use the Pythagorean theorem to find the the hypotenuse, RT:
RT = √[(√2)² + (√7)²]
RT = √(2 + 7)
RT = √9
RT = 3
Using the sine ratio, find sin R:
Sin R = √2/3 = 0.47.

Answer:
510
Step-by-step explanation:
Assume 2 numbers 500,500.. with a mean of 500
so if we add 10 to each of the two numbers, mean will be:
Of course you can vary the set and the numbers and still get the same mean
X = 21
Because we can divide :
-> 72 / 24 = 3
-> 75 / 25 = 3
So it would be something ? / 7 = 3
The answer is 21
