What is the angle measure of an interior angle of an equiangular triangle?

Do you mean equilateral triangle...if yes .. each interior angle will be 60 degree

The goal of writing a number in scientific notation is to have a decimal number, with one digit to the left of the decimal point, followed by a ×10 to some power. To format the number this way, multiply the 0.0003 by 10−by the power of 4 times, making it 3. Each multiplication by 10 moves the decimal point one digit to the left, but in order to keep the same number, multiply 3 by 10−by the power of 4.
