If AC6 and the angle 20 find any missing anges or sides Give
If AC=6 and the angle =20, find any missing anges or sides. Give your answer to at least 3 decimal digits.
AB=
BC=
= 70 degrees
Solution
=20
from the diagram B=90o
SUM OF ANGLES IN TRIANGLE =180o
++B=180o
=180o-20o-900
=700
by law of sines AB/sin() =AC/sinB
AB/sin(20o) =6/sin90o
AB/sin(20o) =6/1
AB =6sin(20o)
AB =2.052
by law of sines BC/sin() =AC/sinB
BC/sin(70o) =6/sin90o
BC/sin(70o) =6/1
BC =6sin(70o)
BC =5.638
