Solve each equation for 0° &lt; x &lt; 360°.
Ipatiy [6.2K]

Answer:

Hence value for x is 0 degree

Step-by-step explanation:

Given:

x limits are (0 to 360) degrees and

Cos(x+45)+cos(x-45)=Sqrt(2)

To Find:

value for X

Solution:

Given equation cos(x+45)+ cos(x-45)

Is similar to cos(A+B) +cos(A-B)=2cosA*cosB

Now comparing with general formula we get ,

A=x and B=45

S

Hence given equation becomes as ,

2cosA*cosB=Sqrt(2)

2Cosx*cos45=Sqrt(2)

cosx=Sqrt(2)/(2*cos45)..........cos45=1/\sqrt{2}

Cosx=Sqrt(2)/Sqrt(2)

cosx=1

x= 0

Hence value for x is 0 degree

Pls halp<br><br>What is the relationship between ∠a and ∠b?
mafiozo [28]

The relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.

<h3>What are complementary angles?</h3>

The angles when added give the sum of 90 degrees and are called complementary angles. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

In the given figure it is observed that the two angles ∠a and ∠b when added give 90 degrees.

Therefore, the relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.

To know more about complementary angles follow
