I need help on this Plzzz!

24m

Step-by-step explanation:

do pyhtogreom theorm

7^2+b^2=25^2

49+b^2=625

subtract 49 from both sides

b^2=576

square root both sides

b = 24

24 is your height

step-by-step explanation:

where is the questions

(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
