we know that the sum all 3 angles of a triangle is 180. we also know that two angles directly opposite from each other are the same, and that the angle of a striaght line is 180. We see that there is an angle directly opposite from the 39 degrees angle, so the bottom left angle of the triangle is 39, and because there is a line splitting the line or the 180 degrees, we know those two degrees sum up to 180, so 109+a=180, a=71, so the bottom right corner angle is 71, and we know that all 3 angles sum up to 180, so 71+39+34+x=180, 144+x=180, x=$\boxed{36}$

because Morgan can paint a room in 10 hours, she can paint 1/10 of a room in 1 hour, and sophia can paint 1/4 of a room in 1 hour, so 2(x/10+y/4)=y/10+x/4=1. simplifying, we get 4x+10y=2y+5x=20, and we can split that into 2x+5y=10 and 2y+5x=20. now we can just solve:

2x+5y=10
2y+5x=20

2y+4x/5=4
2y+5x=20

21x/5=16

x=$\boxed{\frac{80}{21}}$

160/21+5y=10

5y=50/21

y=$\boxed{\frac{10}{21}}$

Because the lines are parallel, angle 1 = $\boxed{82}$.

similarly, angle 2= 180-a, and a=58, so angle 2 = $\boxed{122}$

because it's a parallelogram, x+x-26=180, or x = $\boxed{103}$, so x+26=$\boxed{129}$

1. wrote b incorrectly

2. y=4x+4

plug c for 30, so F=270/5+32, so F=54+32=$\boxed{86}$

Because I cannot see it, I'm just assuming that another side is right, so 360-(145+65+90)=$\boxed{60^\circ}$

5 apples / 8 friends = $\boxed{\frac58}$
