Circumference = 2.pi.8
Circumference =16.pi
Answer:
Step-by-step explanation:
B
answer is 25
Step-by-step explanation:
for something like this you need to use the law of sins. First identify all the angles. There is a 90 degree angle and a 59 degree angle and those are clear. the missing angle is = 59 + 90 = 149
since a triangle has 180 degrees in total you say 180 - 149 = 31. the missing angle is 31 degrees. so we give the angles names. angle with 59 degrees will be angle A, 90 will be B and 31 will be C. So now we just give the sides names. let's replace that x with an a since it's across angle A. the side along angle B will be named b and the side along angle C will be named c. so you say:
Sin A/ a (sin A over a) = Sin B/b = Sin C/c
Sin A is what we are looking for so we say
59 degrees over/ x = sin 31 degrees/ 13 (we leave out the 90 degrees since we don't know the side and also we are not interested in it)
now we do cross multiplying.
say x ×sin 31 degrees = 13× sin 59
now divide these by sin 31
x = 13 × sin 59 ÷ 31 = 25
A Rubik's cube is, well, a cube.
That means that each if its faces is a square, a quadrilateral with four right angles and four sides if the same length.
If the length of one side is x,
4x=22.2
x=5.55 centimeters.
Hope this helps!

The answer is 6x. You divide 42 by 7. Take out the x. 42 divided by 7 will equal 6.
