Use allfour operations only once without parentheses to write an expression that has a value of 100 only using 3's

There are a lot of ways to write an expression using only 3 to get an answer of 100. Some examples are:

1st example:

3 / 3 + 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3

= 1 + 99

= 100

2nd example:

3 / 3 + 3 * 3 * 3 * 3 + 3 * 3 * 3 – 3 * 3

1 + 81 + 27 – 9 = 100

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
