The mean would be 7 I think I am not sure
sin45=5/x so x is 5/(sin45)
y is 5/(tan45)
question 5 then you just go x= (9sqrt(2)/2)/sin45
i don’t have a calculator rn so just plug it into it
Answer:
140 degree
Step-by-step explanation:
Since the sum total of a polygon is 540 degree, simply subtracts from each degree of the other angles.
540 degree - 110 degree - 85 degree - 125 degree - 80 degree = 140 degree
