Question

in a triangle abc, rightin a triangle ABC right angled at B if angle BAC is equals to 30 degrees BC isequals to 8 cm then ​

Answer 1

Answer:

Step-by-step explanation:

(b) sin 30°=BC/AC

1/2=8/AC

AC=16cm

(c) In right triangle ABC angle B=90°

Therefore, AC^2=AB^2+BC^2

√AC^2-BC^2=AB^2

√256-64=AB

√192=AB

8√3=AB
