(x-25) = 7 multiply 5 to both sides first
-(x-25) = 35 then expand the brackets
-x+25=35 make x the subject now;
-x=10
x= -10
The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides
Therefore,
n = 360°/β = 360°/18° = 20 sides
Answer:
Step-by-step explanation:
what you need to do is look at the question again it say 10 feet above sea level and the other one is 7 feet below sea level. now read your question again hope you find the answer good luck
So first what you want to do is take 98 and subtract it by 48. Which gives us 50. Now what we do is that since we are finding two numbers we would have to divide that by half, which would give us 25. Both of them are now equal. To find the number that makes that difference, we need to add 48 to one of the 25 values. Which would be 73. Meaning that the two numbers are 73 and 25. They both add up to 98 and 73 has a difference of 48 from 25.
