Question

if a triangle has side lengths of 7,4,and 10, what kind of triangle is it? (acute,right,or obtuse)

Answer 1

To test for right triangle:

\[a^2 + b^2 = c^2 \]

\[4^2 + 7^2 = 10^2 \]

16 + 49 = 100

65 = 100

FALSE

Therefore, it is not a right triangle.

Answer 2

so than it is an acute than?

Answer 3

\(a^2 + b^2 = c^2\) -- right triangle

\(a^2 + b^2 > c^2\) -- acute-angled

\(a^2 + b^2 < c^2\) -- obtuse-angled

Answer 4

oh its obtuse

Answer 5

Precisely :)

Answer 6

oh okay thank you! :)

Answer 7

yw :)
