Answer:
basically multiplication, (that quantity) times 5
Step-by-step explanation:
Step-by-step explanation:
Volume of water = volume of container = 12 cm * 18cm * 9 cm
so, volume of water = 1944 cm³ (since its filled full the container)
By the question in cubical container,
or, 1/3 of l³ = 1944 (formula for volume of cube is l³)
or, l³/3 = 1944
or, l³ = 5832
so, l = 18 cm
Length of each edge of cubical container is 18 cm.
angles across each other at a junction, namely vertical angles, are equal.
so the angles right in the middle, where both triangles intersect, are both equal, that means the triangles have that angle in common as well as the angle x°, meaning both triangles are similar by AA.
if both triangles are similar, that means all their interior angles are the same, meaning y = 75°.
now, let's notice something, those tickmarks, meaning each triangle is an isosceles triangle, which have a vertex angle and twin angles.
since all interior angles in a triangle add up to 180°, so 180 - 75 = 105°, subtracting "y" from the 180°, that leaves 105°, to be split evenly between the twin angles of "x" and the one at the junction.
105/2 = 52.5° = x.
The answer is 0.105 or 0.11
