Answer:
21
Step-by-step explanation:
First set up the equation
130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)
then start to solve to find x
130 +2x + 30 + 22 = 180
182 + 2x = 180
-182 -182
2x = -2
/2 /2
x = -1
Then just plug it back into the equation
-1 + 22
21
Answer:
This is the exterior angle theorem, so
x+30+x+22=130
2x+52=130
2x=78
x=39
sooooooooooooo
39+22=61 degrees
61 degrees

Answer:
because it is 3/4 of the entire bag, there has to be a Ratio:
3:4 = 4.5:w
\frac{3}{4} \frac{4.5}{w}
cross mult.
3w= 4.5(4)
3w = 18
divide 3 both sided
18/3=6
w=6
