Question

7. The jib sail of a yacht is

a right triangle that is
attached to the mast
and the prow. The
sail is 15 m high,
and the mast is
4 m from the
prow. How
long is the
forestay?

Answer 1

Pytagora's Theorem

Explanation

a = 4 m

b = 15 m

c = ?

a^2 + b^2 = c^2

√ a^2 + b^2 = c

a^2 = 16 m

b^2 = 225 m

√ 16 + 225 = c

√ 241 = 15.52 m

c = 15.52 m
