A leg of a right triangle can never be greater then the hypotenuse
this formula will tell you if it's a valid right triangle
![{?}^{2} + {?}^{2} = {?}^{2}](https://tex.z-dn.net/?f=%20%7B%3F%7D%5E%7B2%7D%20%2B%20%7B%3F%7D%5E%7B2%7D%20%3D%20%7B%3F%7D%5E%7B2%7D%20)
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.
THE STEPS:
![{3}^{2} + { \sqrt{7}^{2} } = {4}^{2}](https://tex.z-dn.net/?f=%20%7B3%7D%5E%7B2%7D%20%2B%20%7B%20%5Csqrt%7B7%7D%5E%7B2%7D%20%7D%20%3D%20%7B4%7D%5E%7B2%7D%20)
![9 + {2.65}^{2} = 16](https://tex.z-dn.net/?f=9%20%2B%20%7B2.65%7D%5E%7B2%7D%20%3D%2016)
![{2.65}^{2} = 7](https://tex.z-dn.net/?f=%20%7B2.65%7D%5E%7B2%7D%20%3D%207)
![9 + 7 = 16](https://tex.z-dn.net/?f=9%20%2B%207%20%3D%2016)
ANSWER:
8ths are divided by 12.5 so 3 * 12.5 is 37.5
10ths are divided by 10 so 4 * 10 is 40
3/8 is < / = 4/10
bus A takes 25 mins
bus B takes 35 mins
start at 8am
to find =lcm of 25 and 35
LCM of 25 and 35
5 /__25,35
/__5,7
LCM=5×5×7
=175 mins=8hr+175mins=10:55am
