Question 397346

Hi
Note using < for angle does not work in the translation for this site.
|ac| has another meaning than for side lengths of triangles,
might recommend just using  'ac'
In a triangle abc,|ac|=16cm,|bc|=10cm, &#8736;bac=30 degrees. If &#8736;abc = 90 degrees, find |ab|
 ac is across from the right angle and therefore length 16cm is the hypotenuse
Pythagorean Theorem applies:  ac = sqrt(16cm^2 - 10cm^2) = 12.49cm
