Question

if triangle ABC is right angled at C,them find value of AB 90​

Answer 1

Answer:

A + B + C=180°

A+B+90°=180°

A+B=90°

Answer 2

Step-by-step explanation:

as sum of angles of traingle is 180°

so , angle A + angle B + angle C =180°

here angle C =90°

so , A + B + 90° = 180°

hence , A+B = 180 - 90

A+B= 90°
