I assume that points BC is a straight line and that D is the point where the line DE intersects BC. If this is so, and CDE is 55 degress, then BDE is 125 degrees.

What type of triangle is this with 55 70 and 55 degrees?

The triangle with angles measuring 55 degrees, 70 degrees, and 55 degrees is an isosceles triangle. This is because it has two angles that are equal (the two 55-degree angles), which also means the sides opposite those angles are of equal length. Additionally, since the sum of the angles equals 180 degrees, this confirms it is a valid triangle.


What is the angle of incidence if a reflected wave bounces off a mirror with an angle of reflection equal to 55 degrees?

The angle of incidence is equal to the angle of reflection according to the law of reflection. Therefore, if the angle of reflection is 55 degrees, the angle of incidence is also 55 degrees.


Determine the measure of angle A if 0 degrees is smaller than or equal to A which is smaller than or equal to 90 degrees and cos125 degrees equals negative cos A?

cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.


What quadrant in standard position is -305 degrees?

-305 degrees would be equal to 55 degrees, which can be found in quadrant one in the standard position.


What is a triangle measuring 55 degrees 45 degrees and 80 degrees?

A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.
