PLEASE HELP!!! I NEED ANSWER IMMEDIATELY!!!<br><br> What is the value for y?<br> y =
34kurt

Answer:

y = 28 degrees

Step-by-step explanation:

First thing:  find the value of x.  Note that the 34 degree angle and the angle x - 5 are equal because this is an isosceles triangle.  Thus, 34 = x - 5, and so x = 39.

Second:  the three interior angles must add up to 180 degrees.

Thus, 34 + 39 -5 + 4y = 180.

From this we get:

4y = 180 - 34 - 39 + 5, or

4y = 112.

Therefore, y must be 112/4, or 28.
