In ABC AB=6ROOT3 AC=12 BC=6 then find angleA
Answers
Answer:
Angle a = 60 degrees
Step-by-step explanation:
okay so ,
first of all ..
IN triangle ABC : AB=
AC=12
BC=6
solution,
by using (30-60-90) degrees theorem,
if angle C= 30 degrees then
SIDE OPPOSITE TO 30 degrees= AC * 1/2
= 12*
= 6 = BC
SIDE OPPOSITE TO 60 degrees= AC×
= 12 ×
= =AB
HENCE angle a =60 degrees
Answer:
Angle a = 60 degrees
Step-by-step explanation:
okay so ,
first of all ..
IN triangle ABC : AB=6\sqrt{3}63
AC=12
BC=6
solution,
by using (30-60-90) degrees theorem,
if angle C= 30 degrees then
SIDE OPPOSITE TO 30 degrees= AC * 1/2
= 12*\frac{1}{2}21
= 6 = BC
SIDE OPPOSITE TO 60 degrees= AC×\frac{\sqrt{3} }{2}23
= 12 ×\frac{\sqrt{3} }{2}23
= 6\sqrt{3}63 =AB
HENCE angle a =60 degrees
