Final answer:
To find the side r in triangle RST with angle R = 37 degrees and hypotenuse s = 15.3, use the sine function. The length of side r is approximately 9.2 units.
Step-by-step explanation:
To find the side r of triangle RST where R=37 degrees and s=15.3 (given that it's the hypotenuse), we can use the sine of angle R to find the opposite side, s, when angle S is the right angle. Using the sine function:
- sin(R) = opposite/hypotenuse
- sin(37) = r/15.3
We calculate r as follows:
- sin(37) ≈ 0.6018
- 0.6018 = r/15.3
- r = 0.6018 × 15.3
- r ≈ 9.2
The length of side r is approximately 9.2 units.
