Answer:
p = 30/1/3 or 91/3 or 30.33
Step-by-step explanation:
2 + p = 7/3 + 30
p = 32/1/3 - 2
p = 30/1/3
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
