Cedric and Insha solved the same equation using the calculations below. Cedric’s Work Insha’s Work z minus 4.5 = negative 1.5. z minus 4.5 + 4.5 = negative 1.5 + 4.5. z = 3. z minus 4.5 = negative 1.5. z minus 4.5 + (negative 4.5) = negative 1.5 + (negative 4.5). z = negative 6. Which statement is true about their work? Cedric is correct because he used the inverse of subtraction and added 4.5. Cedric is incorrect because he should have subtracted 4.5 from both sides instead of adding. Insha is correct because she added the opposite if 4.5, which is Negative 4.5, to both sides. Insha is incorrect because she did not add Negative 1.5 + (negative 4.5) correctly.

step-by-step explanation:

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
