We have been given an equation
. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.
Since x is greater than, so we will take positive root on both sides of our given equation as:


Upon looking at our given choices, we can see that option C is same as our answer.
Therefore, option C is the correct choice.
Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
