Natalie is completing construction of an equilateral triangle inscribed in a circle, as shown below: What should be the next step in her construction? A
Construct a line perpendicular to the line AB to create four congruent quadrants
Construct six equal sections around the circle using the original radius as a guide
Construct another point C anywhere on the circle to be the third vertex of her triangle
Draw arcs above and below line AB to show where the triangle sides meet

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
