calculate the length mn.

The Length of MN is 15.6 cm.

Step-by-step explanation:

Given:

A right angled triangle LMN at angle M is equal to 90°

LN = Hypotenuse = 16.9 cm

LM = Shorter leg  = 6.5 cm

To Find:

MN = Longer leg = ?

Solution:

In Right Angled Triangle Δ LMN

Pythagoras Theorem States that

By applying Pythagoras theorem we get

The Length of MN is 15.6 cm.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
