4=3i ----> (4,3) 6-2i ------> (6,-2)
x1 y1 x2 y2
(4 , 3) (6 , -2) d=√(x2-x1)^2 +(y2-y1)^2
d=√(6-4)^2+(-2-3)^2 -----> d=√2^2+(-5)^2 ----> d=√29
2(420) + 2(245) = x
840 + 490 = x
x = 1330 yards

Answer:
The angle the ladder makes with the wall is equal to 
Step-by-step explanation:
Let
x-------> the angle the ladder makes with the wall
see the attached figure to better understand the problem
we know that
In the right triangle ABC
we have
substitute
To find the answer, we can first find how much the hieght would be lengthened when one is casted as a shadow, by dividing the length of shadow by the height of Kris:
4÷1.5
=8/3
As the height of the object would be lengthened 8/3 times when casted as a shadow, we can then find the length of the statue by its shadow:
12÷8/3
=4.5m
Therefore the answer is C)4.5m.
Hope it helps!
