Find the length of the base of the following pyramid, given the height of the pyramid is 91 meters and the angle of elevation of the base of the pyramid is 52°. round to the nearest whole number. an image of a square pyramid is shown with a right triangle embedded inside it. the face is at an incline of 52 degrees. the height is labeled 91 and the corner of the right angle is marked with a letter p. 142 meters 197 meters 231 meters 295 meters

Step-by-step explanation:

yea its 142 feet and i should have looked at the comments because i failed the test >:(

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
