Question

In the right angled triangle ABC, angle B=90 degree and tan c = 1 then angle A is

Answer 1

Step-by-step explanation:

As we know that sum of all angles of triangle is 180 degree

and it is given that angle B =90 and tan c=1

by using trignometric ratios we know that tan45=1

hence angle c=45

Now, Angle A+ Angle B+Angle C=180

Therefore by putting values we get Angle A=45
