Q:
ai The sides of a big triangle measure 100 m each. The sides of a small triangic
measure 10 m less than the sides of the big triangle.
fipd the perimeter of the big triangle. (ii) Find the perimeter of the smail trian
is the ditference between the two perimeters?
Q:
is it at 1530 hours?
Jack drives north at \( 80 \mathrm{~km} / \mathrm{h} \) for 2 hours. He then turns and drives east at the same speed
for 3 hours.
(a) To the nearest degree, what is Jack's true bearing from his original position?
(b) If Jack could drive from his current position straight back to his starting position:
(i) how far would he travel, to the nearest kilometre
(ii) what true bearing should he follow?
Q:
The shorter leg of a right triangle is 9 m shorter than the longer leg. The hypotenuse is 9 m longer than the longer leg. Find the side lengths of
the triangle.
Length of the shorter leg:
Length of the longer leg:
Length of the hypotenuse: \( \square \mathrm{m} \)
Q:
The longer leg of a right triangle is 1 cm longer than the shorter leg. The hypotenuse is 9 cm longer than the shorter leg. Find the side lengths of
the triangle.
Length of the shorter leg: \( \square \mathrm{cm} \)
Length of the longer leg: \( \square \mathrm{cm} \)
Length of the hypotenuse: \( \square \mathrm{cm} \)
Q:
The length of the longer leg of a right triangle is 20 cm more than twice the length of the shorter leg. The length of the hypotenuse is 22 cm more
than twice the length of the shorter leg. Find the side lengths of the triangle.
Length of the shorter leg: \( \square \mathrm{cm} \)
Length of the longer leg: \( \square \mathrm{cm} \)
Length of the hypotenuse: \( \square \mathrm{cm} \)
Q:
The shorter leg of a right triangle is 5 m shorter than the longer leg. The hypotenuse is 5 m longer than the longer leg. Find the side lengths of
the triangle.
Length of the shorter leg: \( \square \mathrm{m} \)
Length of the longer leg: \( \square \mathrm{m} \)
Length of the hypotenuse: \( \square \mathrm{m} \)

Q:
506 Un trapezio isoscele \( A B C D \) ha gli angoli adiacenti
alla base maggiore \( A B \) di \( 45^{\circ} \). La somma della base mag-
giore e del doppio della minore è 21 cm , mentre la som-
ma della base minore e dell'altezza è 8 cm . Determina
l'area del trapezio.
