The interor angles of a triangle have measures 100 degrees 4y+25 degrees and 3y+20 degrees whats the value of y

y = 5

Step-by-step explanation:

The 3 interior angles of a triangle sum to 180°

Sum the 3 given angles and equate to 180

100 + 4y + 25 + 3y + 20 = 180 ← simplify left side

7y + 145 = 180 ( subtract 145 from both sides )

7y = 35 ( divide both sides by 7 )

y = 5

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.
