Step-by-step explanation:
for the relationship of lengths of internal chords the product of both segments of a chord is equal for all intersecting chords.
in our case
(x+8)×8 = 7×16 = 112
8x + 64 = 112
8x = 48
x = 6
so, D-F = x + 8 = 6 + 8 = 14
so, C is correct
I think it’s 90% cuz it’s 45/50 therefore 90/100
Take the length of the larger divide it by the smaller
5/2 = 2.5
ANSWER: x = 130°
EXPLANATION: You must add given angles and then subtract from 180°.
