Question

A 12 meter -tall a pillar casts a shadow that is 9 m long. What is the top of the pillar to the tip of its shadow​

Answer 1

Answer:

15meters

Step-by-step explanation:

The pillar and shadow form a right angled triangle so we can solve this with pythogorean theorum

=$ax^{2} =bx^{2} =cx^{2}$

=$12x^{2} +9x^{2} =c$

=$144+81=c^{2}$

=$\sqrt{225} =c$

=c =15

=15m
