If N = 9 ft, Q = 2 ft, R = 4 ft, S = 9 ft, and T = 3 ft, what is the perimeter of the object?

The perimeter of the object NQRST will be 27 ft.

<h3>What is a regular figure and its perimeter?</h3>

A regular figure with n-sides has n equal sides in it, and they are the only parts of it(that means, nothing more than those equal lengthed n sides).

Suppose that length of each side of that figure be of u units, then we have the perimeter as: A + B + C + D units.

Its the sum of length of the sides used to made the given figure.

Given; If N = 9 ft, Q = 2 ft, R = 4 ft, S = 9 ft, and T = 3 ft, then we need to find the perimeter of the object.

So the perimeter of the object NQRST.

N + Q +R + S +T

= 9 + 2 +4 + 9 + 3

=  27 ft

Therefore, the perimeter of the object NQRST will be 27 ft.

Z divided by 5 1/5 = -10/13
Firlakuza [10]

Z in (-oo:+oo)

Z/5+3 = -35 // + 35

Z/5+3+35 = 0

1/5*Z+38 = 0 // - 38

1/5*Z = -38 // : 1/5

Z = -38/1/5

Z = -190

Z = -190

I think that is the answer. . . . . . .

Hope that helps!

A triangular face of the roof of the garage has two sides
aleksklad [387]

Answer:

The roof does form a right triangle.

Step-by-step explanation:

If it is a right triangle then it will obey the Pythagoras Theorem.

Now  (√186)^2 = (√93)^2 + (√93)^2

              186 = 93 + 93 = 186

So it obeys the theorem and is therefore a right triangle.
