Answer:
49 7/12
Step-by-step explanation:
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground
No, because the sum of the measures shorter legnths of the sides must be greater than the measure of the greatest angle
4+8=12
so therefor the side legnths if you tried to make into a triangle, it would make a line 12 units long
