Answer:
NW = 15.6 cm
Step-by-step explanation:
If ΔLMN ~ ΔNWR then:





Find NW by using Pythagoras' Theorem:

(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
- a = RN = 6 cm
- b = RW = 14.4 cm
- c = NW
Substituting the given values into the formula and solving for NW:




The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.
30 + 60 = 90
The lower left angle needs to be 180 - 90 = 90 degrees.
That angle is split into two angles with one given as 70.
This means X needs to be 90 - 70 = 20 degrees.
x = 20
