Since ∠1 and ∠2 are complementary...they add up to be 90°.

∠1 = (-2x + 54)
∠2 = (8x + 18) we add these two up
   6x + 72 = 90 subtract 72 from both sides
   6x = 18
   x = 3 place the value of x into the ∠2 equation

(8x + 18) = 8(3) + 18 = 24 + 18 = ∠2 = 42°

Secant jkl and jmn are drawn to circle o from an external point ,j. if jk=8,lk=4 and jm=6 what is the length of jn answer

Archy [21]

See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
jk=8,lk=4 and jm=6
jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16
