A plane flying a straight course observes a mountain at a bearing of 31.7 to the right of it's course. At a time the plane is 8 kilometer from the mountain . A short time later, the bearing to the mountain becomes 41.7

6.3

Step-by-step explanation:

8sin(31.7)/sin(41.7)

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

slope is 35 and 20 miles is the y-intercept.
