Question

in triangle abc angle b is equal to 90 degree angle is equal to 30 degree angle C is equal to 60 degree AC is equal to 16 then find BC​

Answer 1

Answer:

angle b = 90°

angle a = 30°

angle c = 60° ( remaining angle of the triangle )

The side opposite to 30° = 1/2 × hypotenuse

BC = 1/2 × AC

= 1/2 × 16

= 8 cm.

The side opposite to 60° = √3/2 × hypotenuse

AB = √3/2 × AC

= √3/2 × 16

=8√3 was cm.

Ans. side BC = 4 cm. Side AB = 8√3 cm.
