Answer:

C(-n, -n)               Option C

Step-by-step explanation:

Here given that four coordinates:

A(n, n)

B(n, -n)

C(-n, -n )

D(-n, n)

Here we need to find the coordinate that is lie on the third quadrant.

The third quadrant is where both the coordinate and the coordinate of a point are negative.

In other words, x and y values both the negative.

For example: (-x, -y)

In given coordinates vertex C have x and y values both are negative.

So, Option third is correct.

C(-n, -n) is correct.

PLz answer before 11:59 pm
Tpy6a [65]

Answer:

SA = 2520 ft^2

Step-by-step explanation:

a = 21ft

b = 29ft

c = 20ft

h = 30ft

SA = 2A_{B} + (a+b+c)h

A_{B} = s(s﹣a)(s﹣b)(s﹣c)

s = \frac{a + b + c}{2}

SA= ah + bh + ch + \frac{1}{2} \sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c4}

SA= (21 * 30) + (29 * 30) + (20 * 30) +

       \frac{1}{2} \sqrt{-(21)^4 + 2(21 * 29)^2 + 2(21 * 20)^2 - (29)^4 + 2(29 * 20)^2 - (20)^4}

SA = 2520 ft^2
