The area of sector AOB in the following image is 28x cm. What is the measurement of the centrul angle labeled x®?

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
