the third side of an isosceles triangle is 8 inches shorter than the other two sides the perimeter of the triangle is 70 inches

dezoksy [38]

Isosceles triangle has 2 sides that are the same length. So what you have is three sides that measure: x, x, and (x-8). 70 = x + x + (x-8).
70 = x + x + x - 8
78 = 3x
x = 26.
and 26 - 8 = 18.
So two of your sides are 26 inches and the last side is 18 inches.

Quadrilateral RSTU has vertices R(1,3), S(4,1), T(1,-3) and U(-2,-1). Is it true or false that this is a rectangle because the d

Alex777 [14]

Given vertices ofQuadrilateral RSTU as R(1,3), S(4,1), T(1,-3) and U(-2,-1).

We need to check if diagonals are congruent.

The coordinates of verticales diagonal RT are R(1,3) and T(1,-3).

The coordinates of verticales diagonal SU are S(4,1), and U(-2,-1),

By applying distance formula:

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

RT = $=\sqrt{\left(1-1\right)^2+\left(-3-3\right)^2}$ = $\sqrt{36}$

RT = 6

SU $=\sqrt{\left(-2-4\right)^2+\left(-1-1\right)^2}$ .

$=2\sqrt{10}$ .

Diagonal RT is not congruent to Diagonal SU.

Therefore, Quadrilateral RSTU is not a rectangle because the diagonals are not congruent.

So, it is False.

What is 1/4 of a 100 yard by 60 yard field

Tema [17]

Ok, im not going to answer it, but I'm gonna tell you what you need to do to get the answer, first, multiply 100 with 60, then take a quarter out, this is a very simple way to do it, and most people just overthink things.
