The sum of all three angles will always be 180 degrees.
Answer:
He can make it with Max's audio goods
44.575 miles < 45 miles
Step-by-step explanation:
The angle of the truck driver = 180 - (60 + 69) = 51°
By using sin Rule:
40/sin51 = Max's auto goods/sin60 = Jimmy's car supply/sin69
∴ Max's auto goods = 40(sin60)/sin51 = 44.575 miles
∴ Jimmy's car supply = 40sin(69)/sin51 = 48.052 miles
∵ The truck driver can travel another 45 miles
∴ He can make it with Max's audio goods because 44.575 < 45
2x -4y= 28
⇒ -4y= 28 -2x
⇒ y= (28 -2x)/ (-4)
⇒ y= 28/(-4) -(2x)/ (-4)
⇒ y= -7 + 1/2x
The final answer is y= -7 + 1/2x~
