How many acute angles are in an acute triangle

When turned about its axis of rotation, which shape could have created this three-dimensional object?

What is the value of p in the equation y^ = -4x?

❤️ (geometry) does the construction demonstrate how to copy an angle correctly using technology a) yes; the distance between points a and f was used to create circle h b) yes; the distance between points f and g was used to create circle h c)no; the distance between points a and f was used to create circle h d) no; the distance between points f and g was used to create circle h
