Step 1: |25 – (-26)|
Step 2: |25 – 26|
Step 3: |-1|
Step 4: The distance between -26 and 25 is 1.

In which step, if any, did Shawnda make a mistake?

Because this is a right triangle, we can use trigonometry in order to solve for the unknown angle.

A good way to remember how trigonometry works is SOH CAH TOA

Sin - Opposite / Hypotenuse
Cosine - Adjacent / Hypotenuse
Tangent - Opposite / Adjacent

Since we've been given the length of the adjacent and opposite side of the angle, we can use tan -1 in order to solve for the angle.

Since trigonometry relies on the value of the angle to solve for sides, we can't use the normal tan in a calculator. Instead, we use tan -1, which essentially allows us to solve for the angle with given lengths of sides.

tan -1(17/41) = 22.52

Because we have to round to the nearest whole number:

The angle is 22 degrees.
