Question

Find the length of AB.

Answer 1

Answer:

AC² = 4²+5² = 16+9 = 25

AC = √25 = 5

BC² = 7²+9² = 49+81 = 130

BC = 11.4

AB = 5+11.4 = 16.4 in

Answer 2

Step-by-step explanation:

if you observe the pic there are two right angled triangles.

The hypoteneuse of triengle 1 = H1

H1^2 = 4^2 + 5^2

= 16 + 25

= 41

H1 = root 41

The hypoteneuse of triangle 2 = H2

H2^2 = 7^2 + 9^2

= 49 + 81

= 130

H2 = root 130

AB = H1 + H2

= root 41 + root 130
