Step-by-step explanation:

so, a triangle is 180 degrees. you know that one angle is 60 degrees.

this is the equation of the triangle

120=3x

x= 40 degrees

Which graph represents the function?
BlackZzzverrR [31]

Answer:

The last one.

Step-by-step explanation:

The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.

The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.

Hence the last graph is the correct one.
