The base of an isosceles triangle is 4/5. The perimeter of the triangle is 4\2\15 what is the length of either of the remaining equal sides

  1 2/3

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.

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'.
