# a straight angle has a complement

Whenever there is an intersection of two lines that creates an angle directly across from each other, these angles are called vertical angles. Ans: We know that sum of two complementary angles is $${90^ \circ }$$.According to the question, $${38^ \circ } + x = {90^ \circ }$$$$\Rightarrow x = {90^ \circ } {38^ \circ }$$$$\Rightarrow x = {52^ \circ }$$Hence, the value of $$x$$ is $${52^ \circ }$$. Complementary angles can be adjacent or non-adjacent. Each angle is a supplement to the other. Consider the figure as shown. Figure 4 A right-angled triangle; notice the presence of the ninety-degree angle. A mirror is an everyday object used by every person. Complement Angle: We have seen 90 deg angle in complementary angle. There is an 80 degree difference between the measure of the supplement of angle A and the measure of the complement of angle A. Can we still refer to them as complementary? The word supplementary came from the Latin word supplere, meaning supply. Supplementary angles and complementary angles are defined with respect to the addition of two angles. When the ray AD is rotated to an angle of 360 to reach the same position, another ray AC is created. angle P + angle Q = 90 = 90 degrees. Thus, the given two angles in the above figure are non-adjacent supplementary angles.
