We know that
in the right triangle ACD
Applying the Pythagoras theorem
AC²=AD²+CD²------> AD²=AC²-CD²-----> AD²=5²-4²---> AD²=9----> AD=3
let
∅=angle CAD
tan ∅=4/3
in the right triangle CDB
the angle DCB is equal to ∅
tan ∅=DB/CD-------> DB=CD*tan ∅------> DB=4*(4/3)----> DB=16/3
AB=AD+DB-----> 3+16/3----> AB=25/3----> AB=8.33
the answer is

Answer:
-4, 3
Step-by-step explanation:
To find x intercepts, set y equal to 0;
0 = 5(x+4)(x-3); when x = -4 or x = 3, y will be zero (these are the x intercepts),
A work applied on the cart = 20.8x0.636
Answer:
Distance from the point to the line will be
Step-by-step explanation:
We have given the equation of the line is y = 2x\
So the equation of line will be y-2x = 0
Point from which we have to find the distance is (-2,1)
Distance from a point to line is given by , here A = -2 , B = 1 and C = 0
And point x = -2 and y = 1
So
So distance from the point to the line will be
