Answers

Answer 1

Answer:

Answer:

188 m

Step-by-step explanation:

$\tan(12) = (40)/(x) \n x = (40)/( \tan(12) ) \n x = 188$

Answer 2

Answer:

Answer:

I think that the other answer is WRONG

tan(12) = $(x)/(40)$

x = tan(12)*40 = 8.5

Step-by-step explanation:

$(sin\left(78\right))/(40)=(sin\left(12\right))/(x)$ = 8.5
