(Will give Brainliest, these are angle relationships) Please help, and show work, what relationship is it and set up an equation for it and then solve. Ty

Answer:
5x+15 = 45
-15 -15
5x = 30
30/5 = 6
x=6
they are complementary angles!
Answer:
These are complementary angles, meaning together they equal 90 degrees!
x=6
Step-by-step explanation:
Step 1: Find what 5x+15 should equal. Since together the angles equal 90, you must subtract 45 from 90.
90-45=45
Step 2: Set 5x+15 equal to 45
5x+15=45
Step 3: Solve
5x+15=45
-15 -15
——————
5x/5=30/5
x=6
Hope this helps! ❤️❤️❤️
