Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8
Answer:
$2100.21
Step-by-step explanation:
If the widow gets 0.125 and the son gets 0.4, together they get 0.525, or 52.5%. If you multiply 4000.4 * 0.525, you get 2100.21, which is a little over half of 4000.
