Question

Please help me!!!!! Geometry work!!!

Answer 1

7) 2 acute angles can sometimes equal an obtuse angle. This is because an acute angle is any angle below 90 degrees and an obtuse angle is any angle above 90 degrees. You could have a 50 degree angle and an 80 degree angle, and those 2 acute angles would make an obtuse angle.

Answer 2

Answer:

number 7:Sometimes  We can have two acute angles, 20 and 30, 20+30=50, which is still acute,   We can have two acute angles, 45 and 45, 45+45=90, which is neither acute nor obtuse. We can have two acute angles, 80 and 80, 80+80=160, which is obtuse.acute angles are less than 90 degrees. However, they can sometimes equal obtuse angles. For example, two acute angles measures of 70 degrees and 30 degrees are both acute. Add them together they equal 100 degrees, which is obtuse. some examples:  40° and 30° are acute angles  40° + 30° = 70°, which is an acute angle  60° and 30° are acute angles  60° + 30° = 90°, which is a right angle  50° and 70° are acute angles  50° + 70° = 120°, which is an obtuse angle.

number 8 :Since the intercepted arc LN is the diameter of the circle, its measure is 180 degrees, so m<LMN = 90

Conclusion: the sum of two acute angles is sometimes an acute angle.
