Answer:
sin75º=sin(30)º+45º)
=sin 30 cos 45+cos 30 sin 45
=1/2*√2/2+√3/2*√2/2
=√2/4+√6/4
=(√2+√6)/4
Check with calculator:
sin 75º≈0.9659
exact value=(√2+√6)/4≈0.9659
Find the square root of 49, which would give you the dimensions of the square.
The square root of 49 is 7.
To find the perimeter: (square has four sides)
7+7+7+7= 28
Therefore the perimeter is 28 inches :)
The answer will definitely be B if you think about it
Answer:
28.
Step-by-step explanation:
The method of calculating Area is by multiplying the length and the width, therefore it would be:
Answer:
Pyramid Volume = (Area of Base * Height) / 3
height = side
Pyramid Volume = (side * side * side) / 3
Pyramid Volume = (side ^ 3) / 3
That's the answer. I don't know which of your answers equals that.
