cosA/cosB =  1

Step-by-step explanation:

We know that cos = Adjacent Side/hypothenuse.

Then Cos(A)= AC/AB = 3/4.24 = 0.707

Cos(B) = BC/AB = 3/4.24 = 0.707

Then cosA/cosB = 0.707/0.707 = 1

The correct answer is

CosA/CosB =1

Step-by-step explanation:

Points to remember

Trigonometric ratios

Cos θ = Adjacent side/Hypotenuse

From the figure we can see a right angled triangle.

To find the value of CosA/CosB

CosA = Adjacent side/Hypotenuse

 =AC/AB = 3/4.24

Cos B =  Adjacent side/Hypotenuse  

 = BC/AB = 3/4.24

CosA/CosB = (3/4.24)/(3/4.24) = 1

Therefore the value of CosA/CosB = 1

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
