Question

find measure of arc SE

Answer 1

Note that chord HG is congruent to chord SE because they are equidistant from the center. Does that help?

Answer 2

and how do i go on from there

Answer 3

how would i find the radius of this

Answer 4

would it be 100

Answer 5

\[\tan 40=\frac{6}{\frac{1}{2}HG}\]

Answer 6

but i dont know the measure of HG

Answer 7

That is exactly the point. Solve that equation for HG

Answer 8

i got measure of arc se is 100 is that correct

Answer 9

\[\frac{1}{2}HG \tan 40=6\]
\[HG \tan 40=12\]
\[HG=\frac{12}{\tan 40}\]

Answer 10

\[HG=\frac{12}{.839}=14.3\]
