Question

Help asap with Arcs! 30 Points

Answer 1

the answer is 15

these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:

`3x + 5 = x + 35 \\ 3x - x = 35 - 5 \\ 2x = 30 \\ x = (30)/(2) = 15`

so EF is = 3(15)+5=50
good luck
