Answer:
167
Step-by-step explanation:
Let n be your first number. Then the second number is 5n; and the third number is n+100. So:
n+5n+n+100=569
$1 = 3.70 rands
$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.
450 * $1 = 450 * 3.70 rands
$450 = 1665 rands
2nd angle measures 50
90 is the total so all that was needed is to subtract 40 from 90
