Question

Дано: F=3H cosA=45* L=94mm A-?

Answer 1

A=F*S*cosa=3*0,094*0,71=0,2 Дж

Answer 2

3Н*0,094м*cos45=0,2Дж

Answer 3

To solve for the angle A, we can use the given equation:

F = 3H cos(A) = 45*

Where: F = Force H = Unknown constant A = Angle in degrees

• = Degrees symbol

Since we have the value of F (which is 45) and the value of H (which is 3), we can rearrange the equation to solve for A:

cos(A) = F / (3H)

cos(A) = 45 / (3 * 3)

cos(A) = 45 / 9

cos(A) = 5

Now, we need to find the angle whose cosine is 5. However, the cosine function can only return values between -1 and 1. Therefore, there is no real angle A that satisfies cos(A) = 5.
