Line segment on is perpendicular to line segment ml. what is the length cord of ml? 20 units 24 unitsline segment on is perpendicular to line segment ml. what is the length of chord ml? 20 units 24 units 26 units 30 units 26 units 30 units

We know that
the segment ON divide the circle into two equals parts
then
MP=PL

in the right triangle MOP
MO=13
OP=ON-PN
ON is equal to the radius of the circle
ON=13
PN=8
so
OP=13-8> OP=5 

applying the Pythagorean Theorem
MO²=OP²+MP²
MP²=MO²-OP²> MP²=13²-5²> MP²=144> MP=12

therefore
ML=2*MP> ML=2*12> ML=24

the answer is
the length of chord ML is 24 units

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
