A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF? triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees

Explanation:

From the description, you know:

1. Angle D.

The measure of the angle D = the measure of the angle A

2. Hypotenuse (side DE)

Since F is the right angle of the triangle, the side DE is the hypotenuse.

3. Segment EF

Angle E is opposite to angle D, hence segment EF is opposite to angle D.

i dont know i just need points
