nice day folks eeeeeeeeeeeeeeeee
Answer:
range : {0, 2, 4}
Step-by-step explanation:
write down the same range once.
Answer: shapes with at least 1 circular face
Step-by-step explanation:
<span>The cosine of an angle is the quotient of the side that angle lay on and the hypotenuse.</span>
x-hypotenuse
cos45=19/x
0.707=19/x, x=19/0.707, x=26.9
Hypotenuse is <span>approximately 27.</span>
Just use proportions for the "corresponding sides" in each
![\bf \cfrac{smaller\ side}{bigger\ side}\qquad \cfrac{25}{50}=\cfrac{x}{48}\qquad \qquad \cfrac{25}{50}=\cfrac{y}{14}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7Bsmaller%5C%20side%7D%7Bbigger%5C%20side%7D%5Cqquad%20%5Ccfrac%7B25%7D%7B50%7D%3D%5Ccfrac%7Bx%7D%7B48%7D%5Cqquad%20%5Cqquad%20%5Ccfrac%7B25%7D%7B50%7D%3D%5Ccfrac%7By%7D%7B14%7D)
then just solve for "x" and "y" respectively
