Step-by-step explanation:

x = 37.2°, 142.8°, 217.2°, 322.8°

Correct to 1 dp

Step-by-step explanation:

cot²x = sqrt(3)

tan²x = 1/sqrt(3)

tanx = +/- 0.7598356857

Basic angle = 37.322886589

x = 37.2°, 142.8°, 217.2°, 322.8°

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
