To find the answer we simply work out the equation.
cos (75) = 10/x
cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.
x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.
The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137
That means that 4 out of 11 people did not have umbrellas
You can write this as a fraction so
4/11 = x/99
Then, multiply both sides by 99 to isolate the variable.
So x is going to equal 99 times 4 divided by 11, which is 36. That means 36 people did not have umbrellas.

Plug in the values for x and y to check.
-6>8-10
-6>-2
Final answer: False
This is because -6<-2. Remember that for negative numbers, the number with the greater absolute value is less.
Answer:
380 + 6 + 14
Step-by-step explanation:
The sum of 386 and 14 is 386 + 14 = 400.
To find which stategy he used, we find the results of each sum, and it has to be 400.
380 + 6 + 14
380 + 6 + 14 = 386 + 14 = 400
So this is the strategy that he could have used.
380 + 14 + 14
380 + 14 + 14 = 394 + 14 = 408
Result different of 400, which means that this was not the strategy
386 + 10 + 4 + 14
386 + 10 + 4 + 14 = 386 + 14 + 14 = 408
Result different of 400, which means that this was not the strategy
386 + 14 + 80 + 6
386 + 14 + 80 + 6 = 400 + 86 = 486
Result different of 400, which means that this was not the strategy
