Question

Please help!!!! Find (i) BÂC (ii)AC (iii)Area ABC (iv)Perimeter Abc

Answer 1

Answer:

2) 14.42 cm (approx)

3) 48cm²

4) 34.42 cm (approx)

Step-by-step explanation:

2) AB² + BC² = AC² (pythagoras theorem)

8² + 12² = AC²

64 + 144 = AC²

208 = AC²

AC = 14.42cm (approx)

3) Area of ABC = 1/2 × BC × AB

arABC = 1/2 × 12 × 8

arABC = 48cm²

4) Perimeter of ABC = AB + BC + AC = 8 + 12 + 14.42= 34.42cm (approx)

(sorry i do not know first one)
