For a given right triangle, side a =400 feet and side b = 900 feet, what is the measure of angle a to the nearest degree.

Use A²+B² = C²

so you get sqrt 400 * 400 + 900 * 900
sqrt of 160000 + 810000
or sqrt of 970000
which is 984.9 feet

Given number : travelling 45 miles /hours
Find the number of minutes will you spend if you travel 240 miles from Orlando to Miami
=> in 1 hour there are 60 minutes
=> 45 miles / hours is also equals to 45 miles / 60 minutes
=> how many 45 are their in 240
=> 240 / 45
=> 5.3, round to the nearest whole number = 5
=> 5 x 60
=> 300 minutes
=> 240 /300 minutes
