Question

Line segment ON is perpendicular to line segment ML.

What is the length of chord ML?

A) 20 units
B) 24 units
C) 26 units
D) 30 units

Answer 1

The answer is B. 24 units

Answer 2

24 units

Explanation:

OM = ON, so

OP= 13-8

That means OP is 5.

Using the Pythagorean Theorom to find MP:

5^2+b^2=13^2

25+b^2=169

b^2=169-25

b^2=144

B=12

This means MP =12. ML is twice as long as MP. 12x2=24
