A triangle with angle measures of 20 ° and 30 ° is (choose) triangle.

Options for choose
An acute
An obtuse
A right

Respuesta :

A triangle's angles add up to 180 degrees.

Add the angles you know together.

20+30= 50

180-50= 130

130 is greater than 90 degrees.

Therefore, the triangle is obtuse.

I hope this helps!
