Question

in a right angled triangle ABC ,angle b=90 degree if AB =8 ,BC=15 find the perimeter of triangle ABC

Answer 1

Answer:

40

Step-by-step explanation:

Pythagoras theorem -

8² + 15²= x²

64 + 225 = x²

289 = x²

17= x

perimeter = 40

Answer 2

Answer:

By Pythagoras theorem

(Hyp)² = (Base)² + (perp)²

( AC)² = (AB)² + (BC)²

(AC)² = 8² + 15²

(AC)² = 64 + 225

(AC)² = 289

AC = 17

Perimeter = Sum of all sides

AB + BC + AC = Perimeter

8 cm + 15 cm + 17 cm

40 cm is the Perimeter
