Question

In a ∆abc right angled at angle b ac = 8 cm bc = 4 cm find angle a and angle c​

Answer 1

Answer :

Angle (A)=30° and Angle(c)=60°

solution step by step:

in triangle ABC

AC=8cm, BC=4cm

Angle b=90° then angle c=? and angle A=?.

let angle (theta)=C

Cos(c)=b/h

=4/8

=1/2

angle(c)=60°

let angle (theta)=A

sinA=p/h

=4/8

=1/2

Angle(A)=30°
