Here is the answer.
You just have to remember the given formula.
Answer: 11.1 m
Step-by-step explanation:
This can be solved by the Pythagorean theorem where;
c² = a² + b²
c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.
a is the height
c is the length
32² = 30² + b²
b² = 32² - 30²
b² = 1,024 - 900
b² = 124
b = √124
b = 11.1 m
Answer:
interior angle=5&3 and4&6
exterior angle=5&2,6&1,3&8,4&7
20% Because $18.00 - $14.40 = $3.60
3.6/18 = 0.2 ---> 20%
