Sally states that a triangle can only have one obtuse or right angle. However, a triangle must have at least two acute angles. Is Sally correct? Explain.

Sally is correct. The sum of the measures of the three interior angles must add up to 180 degrees. If a triangle had more than one right or obtuse angle, then the sum of the measures would be over 180 degrees. So two of the angles must be acute.

This is the correct answer.

She is correct because the sum of the measures must add up to 180 degrees. If a triangle had more than one right or obtuse angle, then the sum of the measures would be over 180 degrees.

This is a shorter and different version from the sample response.

Incase you were wondering this works too.

Hope this helps!!!

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
