The price of a toy usually costs £50 is increased to £65 work out the percentage increase

Step-by-step explanation:

10% of 50 = 5

5% of 50 = 2.5

to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65

u have used 30% so the answer to yr question is 30%

(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
