Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!
---
∠K = 3(7)+3 = 24
∠L =10(7)-4=66
THE 5 IDENTICAL SHELVES WOULD have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer
