If a, b and c are the lengths of a right triangle and c is the longest side, then:

We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:

<h3>Answer: It's the right triangle.</h3>
Answer: x = 21; y = 29.5
because 2y° and 59° are 2 opposing angles ⇒ 2y° = 59° ⇔ y = 29.5°
we also have: (3x - 4)° = 59° ( because of 2 parallel lines)
⇔ 3x = 59 + 4 = 63
⇔ x = 63/3 = 21
