A baker bought some butter. He used 360 grams to make some pastry. This was 5/6 of the butter he had. How much butter did he buy at first?

he bought 432 grams of butter

Step-by-step explanation:

360/5=72 grams

72x6=432 grams

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
