<h3>Simplifying an Expression</h3>
From the question, we are to simplify the given expression
The given expression is
53 -2(16/8 * 16-7)
Simplifying
Using BODMAS
53 -2(16/8 × 16-7)
53 -2(2 × 16-7)
53 -2(32-7)
53 -2(25)
53 -50
= 3
Hence, the simplified form of the expression is 3

Answer:
The answer is 12.64 ft.
Step-by-step explanation:
From the figure it is clear that slope is the hypotenuse which we have to find while the other two sides are legs of the triangle whose lengths are known.
so the pitch of the roof is 12.64 ft. i explained in the figure below as well.
That's not a squre
anyway, we use ratios
base:person to corner=28:8
height to height=x:5
so
28/8=x/5 becasue same ratio
28/8=14/4=7/2
7/2=x/5
multiply
35/10=2x/10
35=2x
divide 2
17.5=x
x=17.5 feet
