Answer:
Step-by-step explanation:
Remark
The sine of an angle involves the Hypotenuse. So the first job is to find that.
When you do Sin(H) = opposite / hypotenuse
Hypotenuse
Givens
a = √3
b = √13
c = ?
c is the hypotenuse.
Equation
c^2 = a^2 + b^2 Substitute values
Solution
c^2 = (√3)^2 + (√13)^2
c^2 = 3 + 13 Combine
c^2 = 16 Take the Square Root of Both Sides
√c^2 = √16
c = 4
Sin(H) = opposite / Hypotenuse
Opposite = √3
Hypotenuse = 4
Sin(H) = √3/4
Sin(H) = 1.7321/4
Sin(H) = 0.4330
Answer
Sin(H) = 0.43
