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:1/12 or 8.3
Step-by-step explanation:
Answer:

Step-by-step explanation:
We have been given that on a compass, due east is a 1/4 turn clockwise from due north.
Since we know that a compass is in form of a circle and the measure of degrees in a circle is 360 degrees.
To find the number of degrees in a one-fourth turn, we will divide 360 by 4.
Therefore, there are 90 degrees in a 1/4 turn of compass.
Answer:
y-7=-4(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
y-7=-4(x-(-2))
y-7=-4(x+2)
Sin(x) = base / hypotenuse
sin(x) = 7/9
x = arcsin(7/9)
x = 51 degrees
