Question

The legs of a right triangle measure 8 cm and 6 cm respectively. How long is the longest side of the triangle?

a.12
b.10
c.14
d.11

Answer 1

b. 10

Explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is:
`\sqrt{a^(2)+b^(2) }` where a and b are the legs of the triangle.

Longest side of triangle =
`\sqrt{8^(2)+6^(2)}`

=
`√(64+36)`

=
`√(100)`

= 10
