Which angle is congruent to angle 3 and explain why I will give a brainless for a correct answer :)

Angle 6

Step-by-step explanation:

One easy way to know if an angle is congruent is it being directly across from the angle. In this case its fairly easy to tell since (assuming) that angle 3 is a 90 degree angle and so is angle 6.

q: 92 degrees

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'.
