A square has 4 sides.
If the perimeter around the square is 12cm, then you do 12 ÷ 4, which is 3.
Each side is 3cm long.
Linear line formula: y = mx + b
m = slope
b = y-intercept
In this case the question gives us what we need to substitute.
m = 4
b = 3
y = 4x + 3

Answer:
It is 40 degrees
Step-by-step explanation:
The 2 lines, x and y are forming 90 degrees, and since we know that part of that complementary angle is 50 degrees, we would do:
