What are the values of s and t?

Answer:
w = 48
x = 66
Step-by-step explanation:
The triangle in your picture is an isoceles triangle, meaning that IH = JH.
Which means that angle I is equal to angle J or x = 66.
Now you just have to add up all three angles to 180 degrees.
66 + 66 + w = 180
132 + w = 180
w = 48
