A, b, and c are collinear, and b is between a and c. the ratio of ab to ac is 4: 5. if a is at (-3,7) and b is at (1,-5), what are the coordinates of point c?

Step-by-step explanation:

AB:AC=4:5

AB:BC=4:5-4 OR 4:1

So B divides AC in the ratio 4:1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
