Answer:
2
Step-by-step explanation:
The products of chord lengths are the same for the intersecting chords:
AQ×BQ = CQ×DQ
6×12 = CQ×(38 -CQ)
This gives a quadratic in CQ:
CQ² -38CQ +72 = 0 . . . . . write in standard form
(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic
CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero
The minimum length of CQ is 2 units. (DQ will be 36.)
7.8 = 0.65x
x = 100/65 * 78/10
x = 10/5 * 6
x = 12
It is 100 times more than 0.8 and 10 times more is 8. to find it out u have to go 2 places to the left and u will get 100
180-92=88 the answer is 88 because a line is equal to 180 degrees and you got one angle equaling 92 degrees so you just subtract 180 minus 92, getting you angle 8 to be 88 degrees
B 2,_2 is the answer that i get
