Which is a correct definition for a right angle? a. an angle with a measure that equals the measure of a square corner b. an angle with a measure that is less than the measure of a square corner c. an angle with a measure that is greater than the measure of a square corner d. an angle that looks like a line

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

yes because they have the same amount of green and blur marbles.
