Well we know that the circle is equal to 360 and it is cut in half by JM but we also know that NM is the same as MK and half of 360 is 180 and 180 -55 =125 so jk equals 125
Answer:
y = -17
Step-by-step explanation:
3y + 20 = 3 + 2y
Collect like terms
We have 3y - 2y = 3 - 20
y = -17
Answer:
About 53.13 degrees.
Step-by-step explanation:
If we draw the path of the hiker, or rather, all three vectors with vector B having its starting point at the end point of vector A, a right triangle is formed. We will most likely be using trigonometric functions to solve this.
vector A is parallel to the x axis (West - East), and vector B is perpendicular, so we'll be using the inverse tangent function to get the angle based on the ratio of the lengths of vector B to vector A, which is 
atan
degrees.
If one would be pedantic, they'd say that the direction we have to go to get from vector C to vector A is clockwise, which is anti-mathematical, the true answer would be -53.13 degrees. Alternatively, whatever 360-53.13 is.
