Answer:
6.3 ft
Step-by-step explanation:
The ladder lying on the wall with an elevation of 39° forms a right angled triangle.
Hypotenuse = length of ladder = 10 ft
Opposite = x = ?
θ = 39°
Use trigonometric ratio formula to find, x, which is how far the ladder goes up the wall.
The trigonometric ratio formula to use is:
sin(θ) = opposite/hypotenuse
Sin(39) = x/10
Multiply both sides by 10
10*sin(39) = x
x = 10*sin(39)
x = 6.29 ≈ 6.3 ft (to nearest tenth)

Steps to divide 45 by 15 using integer tiles
Step 1: We start by writing out 45 items;
<em>See attachment 1 where I used 45 boxes as illustration</em>
Step 2: Then, we group these 45 items into groups (15 per groups)
<em>See attachment 2 for illustration</em>
<em />
Step 3: Count the number of groups
There are 3 groups;
Hence, 45 / 15 = 3
