Question

In a triangle ABC, angle B is 90 deg. If AB = (x-1) cm, BC = (x + 6) and AC = (x + 7) cm. Find the length of each sides.

Answer 1

Step-by-step explanation:

The sum if All angles in triangle=180°

AB+BC+AC=180°

(x-1)+(x+6)+(x+7)=180°

x-1+x+6+x+7=180°

3x-12=180°

3x=168°

x=56°

Hence,AB=55°

BC=62°

AC=63°
