Asquare stained glass window is divided into four congruent triangular sections by iron edging to represent the seasons of the year. each diagonal of the square window measures 9 inches.

what is the approximate total length of iron edging needed to create the square frame and the two diagonals?

43.5 inches
50.9 inches
54.0 inches
61.5 inches

Option A

Step-by-step explanation:

Given that a square stained glass window is divided into four congruent triangular sections by iron edging to represent the seasons of the year

Each diagonal = 9 inches

Using Pythagorean theorem for right triangle with two sides and one diagonal we get

Iron rods needed for square with two diagonals

= perimeter of square + length of 2 diagonals

=4s+2d

=4(6.363)+2(9)

=43.452

Rounding off gives

43.5 inches Option A

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
