Question

Solve each equation for 0°; x=360 sr2 cos x +1=0

A. 45°, 315°
B. 115°, 245°
C. 135°, 225°
D. 46°, 314°

Answer 1

To solve the equation x = 360 - √2cos(x) + 1 = 0 for 0°, we substitute x = 0° into the equation and solve for √2cos(0°). There is no solution to the equation for x = 0°.

Step-by-step explanation:

To solve the equation x = 360 - √2cos(x) + 1 = 0 for 0°, we need to find the values of x that satisfy the equation when x = 0°. Let's substitute x = 0° into the equation:

360 - √2cos(0°) + 1 = 0

360 - √2 + 1 = 0

Now, solve for √2cos(0°):

√2cos(0°) = 360 + 1

√2 = (360 + 1)/cos(0°)

Since cos(0°) = 1, we have √2 = 361.4142

Therefore, there is no solution to the equation for x = 0°.
