Answer:
38
Step-by-step explanation:
Line KP is equal to 180 degrees.
The square on angle OLM means that angle is equal to 90 degrees.
Let angle PLO be represented as x.
That would make our equation be 52 + 90 + x = 180.
Start simplifying down to get x by itself.
180 - 90 = 90
52 + x = 90
90 - 52 = 38
x = 38
The unit rate is -1/3.
In direct variation, y varies directly to x by a constant ratio k.
Its equation looks like this: y = kx ; where k stands for the constant ratio.
In the above equation. x = -3y, it should be converted to the proper equation. both sides must be transferred and its accompanying sign must be changed.
3y = -x
3y/3 = -x/3
y = (-1/3)x
where: y is the total value; -1/3 is the unit rate; and x is the number of units
