A right angle is a measure of 90 degrees or a 1/4 of a turn
It is pi/4 radians.
It is: 40 degrees and 90 degrees respectively

Since there is no information on any length it is not possible to answer the question.
Types of angles according to measure: 1. Acute angle- angle measure is less than 90 degrees 2. Right angle- angle measure is 90 degrees 3. Obtuse angle- angle measure is more than 90 degrees but less than 180 degrees. 4. Straight angle- angle measure is 180 degrees 5. Reflex angle- angle measure is more than 180 degrees but less than 360 degrees
Angle ABD = 4x - 4 Angle ABC = twice angle ABD = 7x + 4 So 7x + 4 = 2*(4x - 4) = 8x - 8 So x = 12 Then angle DBC = half of angle ABC = 1/2*(7*12 + 4) = 1/2*88 = 44 degrees.
A regular polygon with 4 sides is a square. The measure of any interior angle of a square is 90 degrees.
A right angle is a measure of 90 degrees or a 1/4 of a turn
It is pi/4 radians.
