The measure of angle A is 50 degrees.
2x-10+x+30+70=180
3x+90=180
-90 -90
3x=90
x=30
2(30)-10
60-10
50
So we have W/-1.3 (w over -1.3) then = -6.2
It would look like: W/-1.3 = -6.2
Put -6.2 over 1 so it looks like W/-1.3 = -6.2/1
Then cross multiply so W x 1 is W
-6.2 times -1.3 is 8.06
Therefore, W is 8.06
D: is 9. and you would graph it at 2,9
