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:
2x+100
Step-by-step explanation:
Answer: D
Step-by-step explanation:
Answer:
19 or 21.
Step-by-step explanation:
I swear.
5 + 5 = 10
10 + 5 = 15
15 + 4 = 19
________________
9 + 9 = 18
18 + 10 = 28
28 - 5 = 23
There are two nines so
23 - 2 = 21
