This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.

Step-by-step explanation: slope
I think it’s the last one.
Since to find the reciprocal of a fraction, we invert the fraction. This means that we place the numerator in the denominator and the denominator in the numerator. To get a positive result when multiplying two numbers, the numbers must have the same sign. So reciprocals must have the same sign.
Statement 1 is false.
While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function. It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.
Statement 2 is true.
The domain of a function is all the x-values it encompasses. This function starts at 3 and ends at 8.
Statement 3 is false.
The range of a function is all the y-values it encompasses. This includes all the y-coordinates, but it does not express the range properly. The range is [6, 10].
Hope this helps!!
