4.) Complementary angles add up to 90°.

5.) ∡x is complementary to 138°.

6.) ∡y is supplementary to 147°.

7.) ∠z is vertical to a 105°angle..

Step-by-step explanation:

1.) ∡x is supplementary to 105°. False

2.) The two angles in a linear pair have a sum of 180°.  True

3.) Vertical angles have the same measure. True

4.) Complementary angles add up to 90°.  True

5.) ∡x is complementary to 138°.       False

6.) ∡y is supplementary to 147°.  True

7.) ∠z is vertical to a 105°angle..  True

Hint: Sum of complementary angles are 90

Sum of supplementary angles are 180.

Vertically angles are equal

the correct answer is 45x

9×5=45 then add the x

answer: the anser is 3
