Which are linear pairs? Check all that apply. ∠DAE and ∠EAD ∠BAC and ∠CAD ∠BAE and ∠EAD ∠EAD and ∠DAC ∠CAE and ∠BAD

B). ∠BAC and ∠CAD

C). ∠BAE and ∠EAD

D). ∠EAD and ∠DAC

Step-by-step explanation:

As we know, a linear pair consisting of angles at a single point of the line has a sum of 180° in total. In other words, two supplementary angles together comprise a linear pair. In the given figure, the pair of supplementary angles ∠BAC and ∠CAD, ∠BAE and ∠EAD, and ∠EAD and ∠DAC are the linear pairs as their sum is 180°. Thus, options B, C, and D are the correct answers.

1696 hundred thousand

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
