Answer:
Step-by-step explanation:
115+4n-5=180 degree (being straight line)
110-4n=180
4n=180-110
n=70/4
n=17.5
therefore the value of n is 17.5 degree
substitute the value of n
4n-5
4*17.5-5
70-5
65
Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:
-Use the slope formula and use any two points from those four points in order to find the slope:
-The two points I use are 
and 
for the equation:
So, the slope of the table is 
.
Answer:
5 miles
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length = 4
b = base= 3
c = hypotenuse
4² + 3²
16 + 9 = 25
√25 = 5
Answer:
