Which expression can be used to find the surface area of the following square pyramid?

Mathematics
1 answer:
telo118 [61]3 years ago
8 0

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4.  Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides.  Thus, the total slant surface area is 4(10 units^2), or 40 units^2.  

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.

Answer:

isosceles triangle means all equal sides and sum of interior angles of a triangle have to add to 180deg. if you draw a triangle with 3 equal 60 deg angles and draw a line from the top angle straight down to the bottom line, basically dividing the triangle into two even ones. then you can say the line or bisector line from the angle makes a 90deg with the bottom line across from angle the line is drawn out of. so then that makes two even and equal triangles, then the measure of the angles will be 90deg from bisector line + 60deg from angle untouched + 30deg from bisector angle = 180 degs for sum of interior angles in both triangles now proving the altitude from the base of an isosceles triangle is also the angle bisector of that angle.

Three cards are drawn from an ordinary deck without replacement. Find the probability that all three are Hearts.
shepuryov [24]

Answer:

11/850 or about 1.29%.

Step-by-step explanation:

Prob ( first drawn = heart) = 13/52 = 1/4.

Prob ( second drawn = heart) =  12/51 =  4/17.

Prob ( third drawn = heart) =  11/50.

Required probability = 1/4 * 4/17 * 11/50

= 11/850.
