Triangle ABC has vertices with coordinates A(-1,-1), B(4,0), and C(0.4). Prove that AABC is an isosceles triangle but not an equilateral triangle. [The use of the set of axes below is optional.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320

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
