what is H if sin 0=0.7071 O=5
We can use the Pythagorean identity sin^2(theta) + cos^2(theta) = 1 to find the value of cos 0. Given that sin 0 = 0.7071, we have sin^2(0) = 0.7071^2 = 0.5.
Substituting this into the Pythagorean identity, we have 0.5 + cos^2(0) = 1. Solving for cos^2(0), we get cos^2(0) = 0.5. Taking the square root of both sides, we have cos 0 = ±√0.5.
Since the value of cos 0 can be positive or negative, we cannot determine the exact value of H without additional information.
To find the value of H, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (H) is equal to the sum of the squares of the other two sides.
Given that sin 0 = 0.7071 and O = 5, we can identify that sin 0 = O / H.
Plugging in the values:
0.7071 = 5 / H
To isolate H, we can multiply both sides of the equation by H:
0.7071 * H = 5
Next, we divide both sides by 0.7071 to solve for H:
H = 5 / 0.7071
Calculating this value:
H ≈ 7.071
Therefore, H is approximately 7.071.
