X = -2
y = 2
You can get this by setting the two different y's equal to each other and solving for the x value.
Make everything equal to 360 degrees
x + 73 + 62 + 66 + x + 57 = 360
2x + 258 = 360
2x = 102
x = 51
i think it would be your first choice
We can write a proportion: 15 m is to 12 m as some other height

is to 20 m
So we get




So the second tree is 25 m tall.
