What is the perimeter of this figure

40

Step-by-step explanation:

So far, the Lengths we have are

4, 4, 8, and 4

for the bottom length, add 8 and 4

For the side length, and 4 and 4

so the lenghts are 4, 4, 8, 4, 8, and 12

4+4+8+4+8+12=40

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
