A regular polygon has 15 sides. Find the size of each interior angle. The correct answer and explanation is: To find the size of each interior angle of a regular polygon with 15 sides, you can use the formula: Interior angle=(n−2)×180∘n\text{Interior angle} = \frac{(n – 2) \times 180^\circ}{n} where nn is the number of sides of

Negative stain: the mixture of cells and nigrosin is spread on a slide, then is heat-fixed 3. Endospore stain: forgot to add safranin 4. Gram stain: decolorization, with 95% ethanol,
What is the square root of negative 289 The Correct Answer and Explanation is: The square root of negative 289 is an imaginary number. To express this, we need to involve the imaginary unit iii, where i=−1i = \sqrt{-1}i=−1. To solve for the square root of -289, we can break it down as follows: −289=(−1)×289\sqrt{-289}
