Question

find a angle c angle b

Answer 1

    solution

using

tan30=a/√3   ⇒ a=√3*tan30   ⇒ a=√3/√3=1

⇒a=1

to find the value of c

using pythagoras theorem

c²=√√3²+1²  ⇒c=√3+1 =√4 =2

⇒c=2

to find the other angles

   cosB=√3/2  ⇒ B=cos₋¹(1/2)

 ⇒ B=6o°

⇒ C=180-30-60=90°

 a=1unit   C=90°  and B=60°°
