A theorem states that, between any two rational numbers on a number line, there exists an infinite number of rational numbers. The formula below can be used in a proof of the theorem. In the formula, a, b, and c represent ration numbers. c = a+b/2

Which of these is an equivalent formula, rewritten for a in terms of b and c?

step-by-step explanation:

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'.

i think asking google will you get the answer to that question
