I believe it will be C- 1kg/0.25 because 2.00÷0.25 will give you 8. It should be the same for 8÷1 which will give you 8 also. That means it is porportional. I hope that helps you.
Answer:
Step-by-step
sum of the adjacent angles of parallelogram is supplementary.
Therefore,
Q + R = 180°
4y+7 + 10y-37 = 180°
14y - 30° = 180°
14y = 210°
y = 210°/14
y = 15°
Could not found X in the question.
Since the cotangent function is defined as

we have that the cotangent equals zero at
, because we have

So, the limit simply becomes

180-145 will give you your answer cause when its a triangle they all = 180
so you add 80 + 65 = 145
so 180-145
