Question

On a piece of paper, use a protractor to construct a triangle with angle measures of 30° and 40°.

Answer 1

Step-by-step explanation:

The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!

Answer 2

An angle smaller than 90° is gonna be a acute so your answer is gonna be acute
