Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
we have
we know that
The volume of a cube is equal to
where
b is the length side of a cube
Using a graph tool------> find the roots of the polynomial
see the attached figure
x=4
so
therefore
<u>The answer is</u>
the length side of a cube is equal to (x-4)
Answer: you have to color in the blocks
Step-by-step explanation: For the first one it says 1.47. So you wold shade in one whole square and then fill out 47 tiny blocks in yellow. Then you would shade in 28 little blocks in blue. For the second one you shade in 1.85 in yellow. To do this shade in one whole square and them 85 little blocks. It then says to take away .3 meaning cross out three little blocks that you shaded in. Hope i could help!!!
