Step-by-step explanation:
- (8x-38°)=90° {because of being vertically opposite angles}
- 8x-38°=90°
- 8x=90°-38°
- 8x=52°
- x=52°/8
- x=6.5°
- z°+90°=180° {being linear pair}
- z°=180°-90°
- z°=90°

Answer:
4 pound
Step-by-step explanation:
From the question :
2 gallons of water = 8 pound bag
Number of pound bag per gallon of water ;
Let the number of pound = x
Using cross multiplication, we'll have :
2 gallons = 8 pounds
1 gallon = x pounds
Cross multiply
2x = 8
x = 8 /2
x = 4
Hence, 1 gallon of water mixes 4 pound bag of concrete.
