Question

solve the problem....

Answer 1

#AlexaRousey here!!

In triangle ABC;

=) angle B + angle A + angle C = 180°

=) angle B + 90° + angle C = 180°

=) angle B + angle C = 180°-90°

=) angle C = 90° - angle B

In triangle ABL;

=) angle B + angle BAL + 90° = 180°

=) angle B + angleBAL = 90°

=) angle BAL = 90° - angle B

By eq 1 & 2;

=) angle C = angle BAL

Hence angle BAL = angle ACB.
