Step-by-step explanation:
first we notice that the line RS makes a diagonal in the circle.Since we are given ROP we can find SOP by:
180⁰-125⁰=55⁰
since they are in each others opposite point they are equal so that means that if we try the equation we did before: SOQ =ROP and QOR=SOP
Answer:
The answer is -1.
Step-by-step explanation:
You have to apply gradient formula :

So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :



Step-by-step explanation:
Let the coordinates of point b be (x,y).
Given the coordinates of a (-7,5) and c(5,-1)
Now according to question
ab = 5bc
using distance formula
Solving we can get
'
However, we do need either x or y coordinate of point b to find the other.
