The vertex angle of an isosceles triangle measure 40.whats the measure of the base angle?
Eddi Din [679]
I don't know if my answer is completely correct, but I think it's 100. All triangles add up to 180, and an isosceles triangle has 2 equal sides. 40 would be the 2 sides, and 180 subtracted from 80 equals 100.

A rectangular playground is to be fenced off and divided into two parts by a fence parallel to one side of the playground. 240 f
lozanna [386]
Let's look at the picture, let's imagine that the gray line is the perimeter fence and that the red OR the blue is the one dividing it. We can see that the blue line is longer than the red one, so it will be advantageous, to have a bigger area, to have the dividing fence the smallest possible.
Let's say then that the width (W) is bigger (or equal) to the length (L), so we have:
W \geq L

W+W+L+L+L=240

2W+3L=240

W=\frac{240-3L}{2}
The area is W*L, so we have
A=W*L=L*\frac{240-3L}{2}=\frac{-3}{2}(L^2-80L)=\frac{-3}{2}L(L-80)
this function is a parabola facing down, its zeros are 0 and 80, therefore its maximum is when L=40
hence, L=40 and W=(240-120)/2=60
It will be a rectangle, measuring 60x40 and the divinding fence will be 40
