Answer:
z = 92
Step-by-step explanation:
z = it's opposite angle
You need to figure out another angle in the triangle containing the 42-degree angle.
There are multiple ways to get there, but going from the 95 degree angle is how I will explain.
95 = 42 + 53
So, think the two small triangles are one big triangle.
95 + 39 = 134
180 - 134 = 46
Now back to the smaller one-
42 + 46 = 88
180 - 88 = 92
The opposite angle to z is 92, making z = 92.
