If A is the center of the circle, then which statement explains how segment ED is related to segment FD?

Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles.

A. segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle a.
B. segment ED ≅ segment FD because arc EF ≅ arc GF.
C. segment ED ≅ segment FD because the inscribed angles that create the segments are congruent.
D. segment ED ≅ segment FD because the tangents that create the segment EF share a common endpoint.

22 dimes and 9 nickels

step-by-step explanation:

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
