Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft

Each hiker owes $41 or 4100 cents for the hiking trip.
<u><em>Explanation</em></u>
Cost of each permit is $15. So, the cost of <u>two permits</u> will be:
Cost of each tram ticket is $19. So, the cost of <u>three tickets</u> will be:
Cost of <u>one can</u> of bear spray is $36.
So, the total cost of the hiking trip
As the <u>three hikers</u> are dividing the total costs of the trip <u>evenly</u>, so each hiker owes or 4100 cents.
