A triangle has one angle that measure 45° and one that measures 60°. What is the measure of the third angle?

option a 75°

Step-by-step explanation:

45°+60°+third angle=180°[by angle sum property]

105°+third angle=180°

third angle =180°-105°

third angle=75°

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
