DaIncredible:
i can solve this but without trigonometry
solve it and give answer don't gove comments here if u know to solve it without trigo. then solve..
OK, i was just saying coz if the asker mind then
And give the answer so that the user who have asked question can get two methods to solve the question
Why will he/she mind..??
Ya, why not...I am also asking her solution that how she solved

Hey!!
As we know that the sum of all angles of a triangle is 180°
In ∆ADC,
Angle A + Angle D + Angle C = 180°
60° + 90° + Angle C = 180°
Angle C = 180° - 150°
Angle C = 30°
Now,
In ∆ABD,
Angle D = 90° ( as linear pair)
Angle A = 30° ( as Angle C = 30°)
And Similarly,
Angle A + Angle B + Angle D = 180°
30° + Angle B + 90° = 180°
Angle B = 180° - 120°
Angle B = 60°
HOPE MY ANSWER WAS HELPFUL!!

How can u take Angle A as 30°
U cannot say that angle A = angle C
The two triangle are not congurent
