Step-by-step explanation:
cos(x) = adjacent / hypotenuse
4 x + 30 = 5x + 20
-5x -5x
-x + 30 = 20
-30 -30
- x = -10
x = 10
Relation because a function can not have two ( , ) with the same x value.

Answer:
3n
Step-by-step explanation:
Tricky one! Since we are not given any lengths I will use my intuition.
4*4/2 = 8
5*5=25
(25-8)/25 = 17/25 = 68%
Am I right? Is my intuition correct/ please tell me so thanks!
