Question

Which angles are complementary to each other? Select all that apply.

please help ive been on this IXL assignment for 20 hours.

Answer 1

The answer is the 3rd one. (DFE and EFA)
The reasoning is if you estimated, DE is around 15 degrees and EFA is around 70. added up would be around 90.

Answer 2

The answer is the 3rd one. (DFE and EFA)
The reasoning is if you estimated, DFE is around 15 degrees and EFA is around 70. added up would be around 90. That is estimating though, but that seems like the more practical answer. using a protractor would be better.
