Answer:
Angle D equals 80 degrees.
Since both triangles and angles are congruent, you can use triangle ABC to find the measure of CDE.
ABC has to equal 180 degrees so that means that 30 + 70 + <B = 180
add: 100 + <B = 180
Subtract <B = 80
Angle B equals 80 degrees which also means that Angle D equals 80 degrees.
< 2 = 90 - 49 = 41 degrees
< 4 = 180 - 41 = 138 degrees
The answer is 20.5 feet, because when you draw out the triangle and label the angles and given sides and then use the law of sines, you end up with it.
1 revolution = 360 degrees
360 degrees x 90 revolutions per minute = 32,400 degrees per minute.
1 minute = 60 seconds.
32,400 degrees per minute / 60 seconds = 540 degrees per second.
