Question

Can you just check my answer please??


Given that angle B = (2x-4), find the complement of B.

I got 179 - 2x

is that correct? Thanks.

Answer 1

complementary angles add up to 90 degrees, not 180

so try again :)

Answer 2

90-(2x-4)=?

Answer 3

-2x + 94? @sshayer @thesmartone

Answer 4

and btw thank you! I got those two confused...

Answer 5

Great job! :)

Answer 6

also one way to keep them in mind is that

complementary starts with c and is 90 degrees sum
supplementary starts with s and is 180 degrees sum

and c comes before s, and 90 is less than 180

:P
