Question

If a triangle has 2 sides measuring 10 and 64 then the 3rd side must be less than what value

Answer 1

It must be less than 180º.

Explanation:

A triangle always adds up to 180º which then means that since two angles have already been stated that means the total of those two angles is 74º which you subtract from 180º to get 106º which is the measure of the third angle.
