Sorry I was moving around taking the picture and my handwriting is sloppy. But I hope you understand how I got the answer
Answer:
<u>18°</u>
Step-by-step explanation:
sin 2x=cos zy
m(2x)=72°
cos(π/2-a)=sin a
cos(π/2-72°)=sin72°
cos18°=sin72°
=>m(zy)=18°
431 ≈ 400
115 ≈ 100
400 - 100 = 300
Answer: 1/b6
Step-by-step explanation:
1/2 gallon= .75 grams
1 gallon= 1.5 grams
2 gallons = 3 grams
4 gallons = 6 grams
So
4 gallons is 6 grams
Then we add on a half which is .75 grams
6g + 0.75g = 6.75g
Hope that helps ;•)
