3times a number x, subtracted from 18, is less than −90.

-write an inequality for the statement above
-find the solution set of the inequality
(write the solution using a fraction or integer)

Can you answer my question? will mark brainiest!

1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2. subtraction property of equality 2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90 substitution 3. m∠1 + m∠2 = m∠3 + m∠2 definition of complementary 4. m∠1 = m∠3 given

Which of these angles are complementary? a. 45o and 45o b. 63o and 117o c. 45o and 135o d. 90o and 45o
