What is the simplified form of cos c

cos c = √2

Step-by-step explanation:

Look at the attached picture.

We know that cos c = base/hypotenuse

The value of base is 5

The value of hypotenuse is 5√2

Now plug the values in the formula:

cos c = base /hypotenuse

cos c = 5/5√2

5 will be cancelled out by 5

Then we have the value √2

cos c = √2

b

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
