Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%
6x-3-9x-2
6x-9x = -3x
-3-2 = -5
the the equation is: -3x-5
The angle T1PT2 is 65-37=28 degree
use law of sine: sin37/PT2=sin28/7370, PT2=7370*sin37/sin28
Use a calcuator, I got the answer 9448
B. sin65=PA/PT2, PA=PT2*sin65=9448*sin65=8563
Answer:
3/6 or 1/2.........................
