Answer:
x=30° y=110°
Step-by-step explanation:
80+70=150
180-150=30° 》》》》 angles in a triangle add up to 180°
x=30° opposite angles are equal
180-140=40° angles on a straight line add up to 180°
30+ 40=70
180-70=110°
y=110°
The perimeter of the figure is 50.56 cm.
Solution:
Radius of the quarter of a circle = 8 cm
Perimeter of the quarter circle = 

= 12.56 cm
In figure, one side of the quarter circle is merged with rectangle, so remove one radius from the perimeter of the quarter circle.
Perimeter of the given quarter circle = 12.56 cm – one radius
= 12.56 cm – 8 cm
= 4.56 cm
Perimeter of the rectangle given = (17 – 8) cm + 10 cm + 17 cm + 10 cm
= 9 cm + 10 cm + 17 cm + 10 cm
= 46 cm
Perimeter of the given figure = 4.56 cm + 46 cm
= 50.56 cm
Hence the perimeter of the figure is 50.56 cm.
160 * 8 = 1280 ounces. 1280/64 = 20 half gallons 20*1/2= 10 So you have 20 half gallons or 10 gallons.
2-gallon

The answers are 347 and 865. To solve this problem you set up two equations, x+y=1212 and x-y=518. You then get the second x by itself by adding y to both sides. You then have x+y=1212 and x=y+518. After this you substitute the x into the first equation and have y+518+y=1212. Then simplify to 2y=694 and y=347
Now that y=347 you put it in the original equation. Solve and get that x=865
