Question

In a right triangle ABC, Angle B= 90 degree; Angle C = 45 degree & hypotenuse AC = 16; find the sides BC & AB ?

Answer 1

Answer:

AB = 5√3 cm

Step-by-step explanation:

angle b = 90°

angle a = 30°

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

side opposite to 30° = 1/2 × hypotenuse

BC = 1/2 × AC

= 1/2 × 10

= 5 cm.

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

AB = √3/2 × AC

= √3/2 × 10

=5√3 was cm.

Ans. side BC = 4 cm. Side AB = 5√3 cm
