Question

HELP FAST -- Can the following be angles of a triangle? Why or why not? 20 °, 60°, 100 - 85° , 89° , 6°

Answer 1

Part (a):
The sum of the interior angles of a triangle is 180°.
The given measurements are:
20°, 60° and 100°
Sum of the given measurements = 20 + 60 + 100 = 180°
Therefore, these measurements can form a triangle

Part (b):
The sum of the interior angles of a triangle is 180°.
The given measurements are:
85° , 89° and 6°
Sum of given measurements = 85 + 89 + 6 = 180°
Therefore, these measurements can form a triangle

Hope this helps :)
