Angle QRT is an exterior angle to the triangle. The rule is that the exterior angle of a triangle is equal to the sum of its remote interior angles. Those remote interior angles are angle RTS and angle TSR. So our equation is

. We can remove the parenthesis and simplify by combining like terms to get 9x = 5x + 9 + x and 9x = 6x + 9 and 3x = 9. That means that x = 3.
594 7/25 converted into decimal is 594.28, 89 37/100 converts to 89.37. Add 594.28 and 89.37 together and we get out final answer of 683.65. Convert that back into fraction form and we get (683 13/20) <--- Final Answer
I'm not sure what the stuff in blue indicates. If we ignore that, then the flat horizontal line means the person stays motionless at some distance away from the motion detector. They don't move because the slope = rise/run is zero here, to indicate a zero speed.

<u>Answer:</u>
(2, 7) or (-6, 1)
<u>Step-by-step explanation:</u>
We are given two equations:
; and

Since y is the subject for both the equations so we can put the values of y equal to each other to get:



Factorizing the expression to get:



Putting x = 2 and x = -6 in any of the equations to get the values of y:



and


Therefore, solution to these equation is (2, 7) or (-6, 1).
