Do you have any options? If not, try going with this method to help you understand this problem a little bit better :) Here we go!
-3 + 8(x) - 5 {-8} = ?
8(x) = ? You have to solve this to make it more "easier" if that makes sense
From the looks of it you have to divide by the number, which we call 8
Since, we have only one solution in this problem, the value of "x" is 0
And not all one solution problem(s) always equal "0". .. it can equal any number sometimes
Good Luck!

Answer:
1.05 radians
Step-by-step explanation:
Given that Vanessa is skiing along a circular ski trail that has a radius of 2.5 km. She starts at the 3-o'clock position and travels in the Counter Clockwise direction.
She stops skiing when she is 1.244 km to the right and 2.169 km above the center of the ski trail.
This can be represented as (1.244, 2.169) on a circle of radius 2.5 km.
From the coordinate point (1.244, 2.169) derived, x=1.244 and y=2.169.
By the definition of tangent,
Vanessa swept out approximately 1.05 radians since she started skiing.
