What are the coordinates of the point on the directed line segment from (1, -6) to (8, 8) that partitions the segment into a ratio of 4 to 3?

  (5, 2)

Step-by-step explanation:

Line segment AB is partitioned by point P into segments of the ratio m : n when point P satisfies ...

  P = (mB +nA)/(m+n)

Here we want ...

  P = (4(8, 8) +3(1, -6))/(4 +3) = (32 +3, 32 -18)/7 = (35/7, 14/7)

  P = (5, 2)

The point (5, 2) partitions the segment into a ratio of 4 : 3.

x = 114

Step-by-step explanation:

Remark

You are trying to figure out what the arc is in degrees. The arc formula is

Intersect angle = 1/2( the furthest arc - the smaller closer arc).

Givens

Intersect angle = 66 degrees

Closer arc = x

Further or largest Arc = 246

Solution

66 = 1/2 (246 - x)                  Multiply both sides by 2 and remove the brackets.

132 = 246 - x                        Subtract 246 from both sides.

132 - 246 = - x

- 114 = - x                             Multiply both sides by -1

-1 (-114) = -1 * (-x)

x = 114
