The height of the ladder on the building is 19.77 feet
<h3>How high does the ladder reach on the building?</h3>
Represent the height of the ladder on the building with h
So, the given parameters are:
Angle, x = 64 degrees
Length of ladder, l = 22 feet
The height of the ladder on the building is calculated using
sin(x) = h/l
Substitute the known values in the above equation
sin(64) = h/22
Multiply both sides by 22
h = 22 * sin(64)
Evaluate the product
h = 19.77
Hence, the height of the ladder on the building is 19.77 feet

A community group bought 30 tickets to an amusement park at a total cost of $810. They bought x student tickets for $25 each and y adult tickets for $30 each.
***
let x=number of student tickets bought
30-x=number of adult tickets bought
..
25x+30(30-x)=810
25x+900-30x=810
5x=90
x=18
30-x=12
number of student tickets bought=18
number of adult tickets bought=12
Hope this helps!

The distance Terry needs to run when the winner crosses the finish line is 1. 6 miles.
<h3>How to find the distance Terry needs to run?</h3>
The race was a 10 km race and she has completed 74% of the race when the winner crosses the finish line.
Therefore, the number of more miles Terry need to cover can be calculated as follows:
74 / 100 × 10 = 740 / 100 = 7.4 km
He has covered 7.4 km.
The distance remaining to cover = 10 km - 7.4 km = 2.6 km
Therefore,
4km = 2.48 miles
2.6 km = ?
cross multiply
The distance remaining to cover(miles) = 2.6 × 2.48 / 4
The distance remaining to cover(miles) = 6.448 / 4
The distance remaining to cover(miles) = 1.612
The distance remaining to cover(miles) = 1.6 miles
