Answer 1

Answer:

90degree

Step-by-step explanation:

Let A(5,2) , B(6,-15) and O(0,0)

Slope of AO (m1)=(2–0)/(5–0) =2/5

Slope of BO (m2)=(-15–0)/(6–0)=-15/6=-5/2

m1×m2= (2/5)×(-5/2)

m1×m2= -1 , therefore angle made by the line

joining (5,2) , (6–15) at (0,0) is 90° , Answer

Answer 2

Answer:

Step-by-step explanation:

First calculate the gradient of the line then equate the gradient of line with tan(theta) and hence calculate Tan inverse(gradient)
