Answer:
b = 8
c = 16
Step-by-step explanation:
From the given right triangle,
a = , m(∠B) = 30°
By applying sine rule in the given triangle,
cos(B) =
cos(B) =
cos(30°) =
c = 16
Further we apply tangent rule,
tan(B) =
tan(30°) =
b = 8

(8)squared+b squared=10 squared
64+b=100 subract 64
now fiquere out what sauqered =36
wich is 6 so the last side is 6
