If you look at the pyramid, the pyramid is really just a hexagon with 6 triangles stacked up to each other at the edges, with the hexagon at the bottom.
now, the perpendicular distance from the center of the hexagon to a side, namely the
apothem, is 6√3, and each side is 12 units long, since there are 6 of them that'd be 72 for all, namely the
perimeter.
each of the triangular faces have a base of 12 and an altitude or height of 11, recall that area of a triangle is (1/2)bh, and area of a regular polygon is (1/2)(apothem)(perimeter).
so if we just get the area of the hexagon at the bottom, and the triangles, sum them up, that's the surface area of the pyramid.
Answer:
pi/12 rads
Step-by-step explanation:
We know -pi/12 goes clockwise. Since it goes down pi/12 radians, the answer is simply pi/12 because when it connects to the x axis, it makes an ACUTE angle (which is the reference angle, and is always positive) of pi/12 rads.
These two parallel lines are cut by a transversal, through the properties of a transversal, we know tht opposite exterior angles are congruent.
therefore, set the two angles equal to each other.
-1+14x=12x-17
add 1 to both sides
14x=12x-16
subtract 12x from both sides
2x=-16
divide both sides by 2
x=-8
Answer:
10×10.70=$107 spent on cups
107-293=$186 spent on the jacket
so for the jackets 186= how many they got and much each cost.
u=186÷x
or 186=u the cost of each × x how many they got.
