Solve each equation for 0≤x≤360
cos(x+45°)+cos(x-45°)= √2

0°

360°

Step-by-step explanation:

We want to solve the equation,

We expand using trigonometric identities to get;

Simplify;

Simplify;

Add

Divide by 2

Take cosine inverse;

In the

Also in the 3rd quadrant cosine ratio is positive.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
