Question

A triangle has a width of 9 units and a length of 40 units. What is the length of a diagonal?

Please help me!!!!!

Answer 1

To solve this question, knowing that this is a right triangle since the differences in side lengths are quite large, and thus it cannot be an equilateral triangle, assuming it is a right angle triangle,

Use Pythagorean theorem to solve for the hypotenuse or the length of the diagonal.

C^2 = 81 + 1600
C^2 = 1681
C = 41 units.

The longest side of the triangle is 41 units.
