Answer:

ruler placement postulate is important to define relative positioning between points.

Although both A & C are possible, we don't consider a line to have an "origin". A distance can have an origin, so the answer must be A.

a cylindrical tinfull of engine oil has a diameter of 12cmand the height of 14cm.the oil is poured into a rectangular tin 16cm l

steposvetlana [31]

Find the volume of the cylinder using the formula v = pixr^2 x height

V= 3.14 x 6^2 x 14 = 1,582.56 cubic cm

Area of of the rectangle = 16 x 11 = 176 square cm

The height will be the volume divided by the area

Height =1582.56/176 = 8.99 cm

The height is 8.99 cm ( round off as needed)

Im stuck on this one

ABC is a right triangle, so by Pythagoras' theorem,

$AB^2+AC^2=BC^2\implies BC=\sqrt{4^2+9^2}=\sqrt{97}$

Then by the law of sines,

$\dfrac{\sin A}{BC}=\dfrac{\sin C}{AB}\iff\dfrac1{\sqrt{97}}=\dfrac{\sin C}4\implies\sin C=\dfrac4{\sqrt{97}}$

$\implies C=\sin^{-1}\dfrac4{\sqrt{97}}\approx24^\circ$
