What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?

Daniel [21]

Our angle teta is:
teta = 3pi/4

since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)

sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.

cos(3pi/4) = -√2/2
tan(3pi/4) = -1

Which of the following rational numbers is equal to 3.4? (line above the four)

Travka [436]

Hey there! :D

So, we can just divide all the numbers to figure it out.

31/9= 3.44444444

32/9=3.5555556

33/9= 3.66666777

34/9= 3.777778

The closest number to 3.4 is 31/9. "A" is the correct answer.

I hope this helps!

You found the area of the garden in Part A. Explain briefly, without doing any calculations, how you would find

Luden [163]

The area of a shape is the amount of space on the shape

5/6 of the area is 5/6 multiplied by the area

<h3>How to determine the area of the shape</h3>

To determine 5/6 of the area of the shape, we simply multiply the calculated area by 5/6

Take for instance:

The area of the shape is 60

5/6 of 60 would be:

$\frac 56 * 60 = 5 * 10$

$\frac 56 * 60 = 50$

5/6 of the area that has a value of 60 is 50

Hence, 5/6 of the area is 5/6 multiplied by the area
