step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b. f(x) = –√x + 3this is the correct answer

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
