Given cot A =2/5 and that angle A is in Quadrant I, find the exact value of sinA in simplest radical form ————————————using a rational denominator.

Is 8.50 an answer or no? ?

Idon’t see a picture

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.
