Question

A mall escalator rises to a platform and makes a 25 degree angle with the ground. If the height of the platform 65 feet how long is the escalator (from the ground to the top)?

Answer 1

ok so we just use the pyagram theorem

25^2+65^2=c^2

4850=c^2

the square root of 4850 is 69(*snickers*).6419413859

so the height of the platform is 70 feet
