Question

In a right Triangle ABC angle b is equal to 90 degree.
(a) ab is equal to 6 CM BC is equal to 8 cm find AC.
(b) is AC is equal to 13 CM BC is equal to 5 cm find AB

Answer 1

Answer:

Step-by-step explanation:

a) in right angled triangle b=90 degree ab=6 cm bc= 8cm then  ac=?

ac^2=ab^2+bc^2

ac^2=6^2+8^2

ac^2=36+64

ac^2=100

ac=10 cm

b) ac=13 cm, bc= 5 cm, ab=?

ac^2=ab^2+bc^2

13^2=ab^2+5^2

169=ab^2+25

ab^2=169-25

ab^2=144

ab=12 cm
