You are correct my dad is a math expert!!
The length of the shadow is 14.2 m
Right angle triangle:
Right angle triangle has one of its sides as 90 degrees.
The height of the building is the opposite side of the triangle.
The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.
The length of the shadow is the adjacent side of the triangle.
Therefore,
c² = a² + b²
b² = 35² - 32²
b² = 1225 - 1024
b² = 201
b = √201
b = 14.17
b = 14.2 m
Hence the length of the shadow is 14.2 m.

Answer:
communicative property of addition
Step-by-step explanation:
associative property of addition is (EX) x + (a + 4) = (x + a) + 4
associative property of multiplication is (EX) 5(ab) = (5a)b
communicative property of multiplication is (EX) (2)(a) = (a)(2)
