Question

9. (i) Calculate the lengths of. (a) AB
(b) BC
(ii) Prove the triangle ABC is right angled.
​

Answer 1

Step-by-step explanation:

Ab²=36²+27²

=1296+729

=2025

Ab=45

2)BC=ROOT OF 36²+48²

1296+2304

3600

60

ABC IS RIGHT ANGLED AS IT SATISFY THE PHTHAGOROUS THEOREM

Answer 2

Answer:

verified answer:

Step-by-step explanation:

(a) AB

x²= 36²+27²

x²= 1296+729

x²= 2025

x= √2025

x= 45

(b) BC

y²= 48²+36²

y²= 2304+1296

y²= 3600

y= √3600

y= 60
